Jacob Bekenstein, an Israeli physicist of the Hebrew University, Jerusalem, planted the seeds of a revolution of our understanding of space-time. Using conservative intuitive methods including time-old gedanken experiments, he discovered that black holes have thermodynamical properties such as entropy.Moreover, he found that their entropy was not extensive, unlike that of any other thermodynamical system considered before, but rather is proportional to the surface of their horizon. Furthermore, Bekenstein pioneered the study of black holes by focusing on their information content aspects. This led him to obtain bounds of a holographic nature on the amount of information that can be stored in a given region of space-time.This book contains a series of scientific and personal contributions by his contemporaries who recall the struggle against his ideas and then with them: the fate accompanying many revolutionary ideas. This is followed by original scientific contributions by many of the leaders of current research on black hole physics and holography. They have trodden his path and expanded it. The impact of Jacob Bekenstein''s visionary ideas is just starting to be understood.

Professor Roman Jackiw is a theoretical physicist renowned for his many fundamental contributions and discoveries in quantum and classical field theories, ranging from high energy physics and gravitation to condensed matter and the physics of fluids. Among his major achievements is the establishment of the presence of the famous Adler-Bell-Jackiw anomalies in quantum field theory, a discovery with far-reaching implications for the structure of the Standard Model of particle physics and all attempts to go beyond it. Other important contributions, among many, that one may mention here are the topological mass term in gravity and gauge theories, and the fractionalization of fermion number and charge in the presence of topological objects.Roman Jackiw, a Professor Emeritus at the MIT Center for Theoretical Physics, is the recipient of several international awards including the Dannie Heineman Prize for Mathematical Physics and the Dirac Medal of the ICTP. He is a member of the US National Academy of Sciences and honorary doctor of Kiev, Montreal, Tours, Turin and Uppsala universities.To celebrate his 80th birthday, many students and colleagues of Professor Jackiw have come together to share interesting anecdotes of working with him as well as their latest research, some of it inspired by his work. Edited by his former students Antti Niemi and Terry Tomboulis together with his long-time friend KK Phua, this festschrift volume is a must-have collection for all theoretical physicists.

Frank Wilczek is one of the foremost theoretical physicists of the past half-century. He has made several fundamental contributions that shape our understanding of high energy physics, cosmology, condensed matter physics, and statistical physics. In all these fields his many discoveries continue to play a key role in shaping the direction of modern theoretical physics.Among Wilczek''s major achievements is the discovery of asymptotic freedom, which predicts and explains the ultraviolet behavior of non-abelian gauge theories. The axion, which he co-discovered and named, has emerged as the prevalent candidate for explaining the origin of dark matter in the Universe. His invention of color-flavor locking explains chiral symmetry breaking in high density quantum chromodynamics. His introduction of fractional statistics and anyons are pivotal to our understanding of the fractional quantum Hall effect and form the building blocks of topological quantum computing. His invention of the time crystal concept has catalyzed extensive investigations of dynamical phases of physical systems.Frank Wilczek received the 2004 Nobel Prize in Physics for the discovery of asymptotic freedom. He is also the recipient of several Prizes and honorary awards including the MacArthur Fellowship, the Lorentz Medal of the Royal Netherlands Academy of Arts and Sciences, the Lilienfeld Prize of the American Physical Society, the High Energy and Particle Physics Prize of the European Physical Society, and the King Faisal International Prize for Science of the King Faisal Foundation. He is a member of the National Academy of Sciences, American Academy of Arts and Sciences, and the American Philosophical Society. He is also a foreign member of the Royal Netherlands Academy of Arts and Sciences and of the Royal Academy of Sciences in Sweden.He is currently the Herman Feshbach Professor of Physics at MIT Center for Theoretical Physics. He also holds a professorship at Stockholm University, is a Distinguished Professor at Arizona State University, and is the founding director of the Tsung-Dao Lee Institute and Chief Scientist of the Wilczek Quantum Center at Shanghai Jiao Tong University.This volume serves as a tribute to Frank Wilczek''s legendary scientific contributions, commemorating his 70th birthday and the first 50 years of his career as a theoretical physicist. The contributors include several of his PhD students, close collaborators, and both past and present colleagues.

We have lost one of the giants of the twentieth century physics when Yoichiro Nambu passed away in July, 2015, at the age of 94.Today''s Standard Model, though still incomplete in many respects, is the culmination of the most successful theory of the Universe to date, and it is built upon foundations provided by discoveries made by Nambu in the 1960s: the mechanism of spontaneously broken symmetry in Nature (with G Jona-Lasinio) and the hidden new SU(3) symmetry of quarks and gluons (with M-Y Han).In this volume honoring Nambu''s memory, World Scientific Publishing presents a unique collection of papers written by his former colleagues, collaborating researchers and former students and associates, not only citing Nambu''s great contributions in physics but also many personal and private reminiscences, some never told before. This volume also contains the very last scientific writing by Professor Nambu himself, discussing the development of particle physics.This book is a volume for all who benefited not only from Nambu''s contributions toward understanding the Universe but also his warm and kind persona. It is a great addition to the history of contemporary physics.

''This book presents a timely set of academic and intellectual views on Salam’s scientific passion, contribution and personality, and will be of great interest to academics in the fields of particle physics, high energy physics and scientific history of the developing world.''Contemporary PhysicsIn honor of one of the most prolific and exciting scientists of the second half of the last century, a memorial meeting was organized by the Institute of Advanced Studies at Nanyang Technological University for Professor Abdus Salam''s 90th Birthday in January 2016.Salam believed that ''scientific thought is the common heritage of all mankind'' and that the developing world should play its part, not merely by importing technology but by being the arbiter of its own scientific destiny. That belief saw him rise from humble beginnings in a village in Pakistan to become one of the world''s most original and influential particle physicists, culminating in the 1979 Nobel Prize (shared with Glashow and Weinberg) for contributions to electroweak unification, which forms an integral part of the Standard Model.The book collected the papers presented at this memorable event which saw many distinguished scientists participating as speakers to reflect on Prof Salam''s great passion for the science and achievements.

Professor Kerson Huang was a well respected theoretical physicist, who was also well versed in English and Chinese literature. He was born in Nanning, China, on 15 March 1928, and he was a fellow at the IAS, Princeton, from 1955-1957 before joining the faculty of MIT. He remained there until he retired from teaching in 1999. His research in theoretical physics included works on Bose-Einstein condensation and quantum field theory. In his long and illustrious career, Prof. Huang has worked with many prominent physicists. In 1957, he published a theory known as the hard-sphere model for Bose gases with Nobel Laureates Chen-Ning Yang and Tsung-Dao Lee. With Noble Laureate Steven Weinberg, he studied the ultimate temperature and the thermodynamics of early universe. While he was at Princeton, he also worked with atomic bomb developer J. Robert Oppenheimer. In recently years, Prof. Huang had been a visiting professor at Nanyang Technological University in Singapore, and worked on both biophysics and quantum cosmology.This memorial volume is dedicated to Prof. Huang who passed away peacefully at home on September 1, 2016 at the age of 88. The volume features the recollections of Prof. Huang by his former colleagues and students, including Profs Chen-Ning Yang and Samuel Ting, as well as their reflections on Prof. Huang''s achievements in the various subdivisions of physics.

Stanley Mandelstam (1928-2016) was one of the most influential and respected particle theorists. Coming as a young chemical engineer from South Africa to study theoretical physics in England, he quickly became a leading physicist in his field. With his deep understanding of quantum field theory, he pioneered the development of the analytic S-matrix theory as well as the path-dependent formulations for quantum gauge theories and for quantum general relativity. They are being actively used for the electroweak theory and having their imprints in lattice gauge theory and loop quantum gravity. Also he elucidated the mechanisms for quark confinement in quantum chromodynamics, constructed non-perturbative bosonization methods in 1+1 dimensions, and proved the perturbative finiteness and β=0 of N=4 supersymmetric Yang-Mills theory. His work also led to the discovery of dual resonance models, which in turn became superstring theory. He was a leader in these developments, devoting much of his later years to the proof that the theory is perturbatively finite so it can be considered as a contender for the theory of quantum gravity.He was also a very modest and friendly man, impressing everyone with his sharp intellect as well as his humanity. This volume contains essays written by many of his friends and students, including both detailed reports on his scientific achievements as well as personal reminiscences. Also collected in the volume are some selected reprints of Mandelstam''s early seminal papers and abstracts of selected papers representing the full spectrum of his contributions.

This memorial volume is dedicated to physicist Gerald E Brown (1926-2013) or ''Gerry'' as he was known to his many students, postdocs, colleagues and friends. As written by one of the contributors to this book, ''Gerry was an inspiring father figure for generations of theoretical nuclear physicists and a great human being''.This book covers a wide range of topics in nuclear physics, including nuclear structure, two- and three-body nuclear forces, strangeness nuclear physics, chiral symmetry, hadrons in dense medium, hidden local symmetry, heavy quark symmetry, cosmic neutrinos, nuclear double-beta decay, neutron stars, gravitational waves, renormalization group methods, exotic nuclei, electron ion collider (EIC), and much more. Most of the authors are Gerry''s former students and collaborators.We hope readers will find this book very interesting not only for its physics content but also for the window it gives into Gerry''s personal legacy and humanity. This book has vivid recollections of Gerry at Stony Brook, Princeton and Copenhagen, together with his humor and his very special intuitive way of thinking.

Ludwig Faddeev is widely recognized as one of the titans of 20th century mathematical physics. His fundamental contributions to scattering theory, quantum gauge theories, and the theory of classical and quantum completely integrable systems played a key role in shaping modern mathematical physics.Ludwig Faddeev''s major achievements include the solution of the three-body problem in quantum mechanics, the mathematical formulation of quantum gauge theories and corresponding Feynman rules, Hamiltonian and algebraic methods in mathematical physics, with applications to gauge theories with anomalies, quantum systems with constraints and solitons, the discovery of the algebraic structure of classical and quantum integrable systems and quantum groups, and solitons with the topology of knots.Faddeev''s name is imprinted in many areas of mathematics and theoretical physics, including ''Faddeev''s equations'' and ''Faddeev''s Green function'' in scattering theory, ''Faddeev-Popov ghosts'' and ''Faddeev-Popov determinant'' in gauge theories, ''Gardner-Faddeev-Zakharov bracket'' for the KdV equation, ''Faddeev-Zamolodchikov algebra'' in quantum integrable systems, ''Faddeev-Reshetikhin-Takhtajan construction'' in the theory of quantum groups, knotted solitons in the ''Skyrme-Faddeev model'' and many others.Ludwig Faddeev founded the St. Petersburg school of modern mathematical physics and distinguished himself by serving the mathematics community for over three decades including his leadership of the International Mathematical Union in the period of 1986-1990. He was conferred numerous prizes and memberships of prestigious institutions in recognition of the importance of his work. These include the Dannie Heineman Prize for Mathematical Physics, the Dirac Medal, the Max Planck Medal, the Shaw Prize and the Lomonosov Gold Medal among others.A gathering of contributions from some of the biggest names in mathematics and physics, this volume serves as a tribute to this legendary figure. Volume contributors include: Fields medalist Sir Michael Atiyah, Jürg Fröhlich, Roman Jackiw, Vladimir Korepin, Nikita Nekrasov, André Neveu, Alexander M Polyakov, Samson Shatashvili, Fedor Smirnov as well as Nobel laureates Frank Wilczek and C N Yang.

Geometry and topology have been a fascination in physics since the start of the 20th century. A leading example is Einstein''s geometrical theory of gravity. At the beginning of the 1970s, topological ideas entered areas of condensed matter physics. These advances were driven by new seminal ideas resolving a serious contradiction between experiment and the standard interpretation of a rigorous mathematical theorem which led to the study of new exotic topological phases of matter. Topological defect driven phase transitions in thin, two dimensional films of superfluids, superconductors and crystals have provided great insight into the mechanism governing these topological phases present in those physical systems. Moreover, many of these topological properties remain ''protected'' against disorder and topological distortion perturbations. An example of possible applications of such robustness to perturbations is in the search for encoding information in quantum computers, potentially providing the platform for fault-tolerant quantum computations.In the past four decades, the discovery of topological phases engendered great interest in condensed matter physics. It also attracted the attention of researchers working on quantum information, quantum materials and simulations, high energy physics and string theory. This unique volume contains articles written by some of the most prominent names in the field, including Nobel Laureate John Michael Kosterlitz and Professor Jorge V José. They originate from talks and discussions by leading experts at a recent workshop. They review previous works as well as addressing contemporary developments in the most pressing and important issues on various aspects of topological phases and topological phase transitions.

The name Wang Gungwu is iconic. He is one of the most eminent scholars and historians in Asia today and is renowned for his scholarship on the history of the Chinese diaspora in Southeast Asia, and the history and civilisation of China and Southeast Asia.A well-known scholar aside, Wang Gungwu has been an inspiring educator since he embarked on an academic career first at the University of Malaya and subsequently at the Australian National University before making his mark as vice chancellor of the University of Hong Kong from 1986 to 1995, chairman of the Institute of East Asian Political Economy from 1996 to 1997, and director of the East Asian Institute (EAI) of the National University of Singapore from 1997 to 2007.This book focuses on Wang Gungwu as an educator and scholar. The volume is organised into three parts. The first section highlights the writings of Wang in the field of higher education. There are 24 selected articles in this collection, many of which were previously published in prominent journals. Several essays originated as keynote speeches at conferences. Spanning over a period of more than three decades from 1971 (when he was with the Australian National University) to 2008 (when he was with the East Asian Institute), Wang shares in the essays his perspectives on a broad range of topics — the relationship between the university and community (both of which are not monolithic); the role of universities in Asia as global institutions; the benchmark of excellence in education in the Asia-Pacific region; the state of social science study in Asia; the shifting paradigms and their impact on research and writing; and the role of university in shaping modernity in Asia, etc. Despite the publication dates of yore, the issues discussed are not passé and are in fact of significant relevance to universities today.The second section contains a selection of over 50 books written and edited by Wang as well as those written in honour of him. The selection is not exhaustive but it serves as a quick reference guide for general readers to access the trove of Wang''s works on Chinese diaspora and overseas Chinese; Chinese culture, history and civilisation; Chinese trade; maritime China; China''s ideological battles; the Chinese Communist Party; China''s political economy; China''s reform; China''s external relations; China and the new international order; Chinese world order; migration; nation-building; Hong Kong; Malaya; Malaysia; and, the Iraq War, etc.The third section provides a detailed chronology of Wang Gungwu''s life and his illustrious academic career. Born in Java, brought up in what was then British Malaya, and having lived under Dutch and British colonial administration, the Japanese occupation, the Chinese revolution and the newly independent countries of Malaysia and Singapore, Wang''s extraordinary set of experiences have enriched his writings as one of the leading historians of China and the doyen of scholarship on the Chinese communities of Southeast Asia.

The Conference on Quantum Mechanics, Elementary Particles, Quantum Cosmology and Complexity was held in honour of Professor Murray Gell-Mann''s 80th birthday in Singapore on 24-26 February 2010. The conference paid tribute to Professor Gell-Mann''s great achievements in the elementary particle physics.This notable birthday volume contains the presentations made at the conference by many eminent scientists, including Nobel laureates C N Yang, G ''t Hooft and K Wilson.

Along the way, even as he proposed new quantum numbers to bring order into the zoo, he had fun in naming them. And thus was born Strangeness, Flavor, Hadrons, Baryons, Leptons, the Eightfold Way, Color, Quarks, Gluons and, with Harald Fritzsch, the standard field theory of strong interactions, Quantum Chromodynamics (QCD).He also proposed with Richard Feynman the V-A theory of beta decay. Gell-Mann discovered the Current Algebra, proposed (with Levy) the sigma model of pions and the see-saw mechanism for the neutrino masses.

He has won numerous notable awards including the Enrico Fermi Award, Templeton Prize, Wolf Prize, Pomeranchuk Prize, and Henri Poincaré Prize.

During the last six decades, Yang-Mills theory has increasingly become the cornerstone of theoretical physics. It is seemingly the only fully consistent relativistic quantum many-body theory in four space-time dimensions. As such it is the underlying theoretical framework for the Standard Model of Particle Physics, which has been shown to be the correct theory at the energies we now can measure. It has been investigated also from many other perspectives, and many new and unexpected features have been uncovered from this theory. In recent decades, apart from high energy physics, the theory has been actively applied in other branches of physics, such as statistical physics, condensed matter physics, nonlinear systems, etc. This makes the theory an indispensable topic for all who are involved in physics.The conference celebrated the exceptional achievements using Yang-Mills theory over the years but also many other truly remarkable contributions to different branches of physics from Prof C N Yang. This volume collects the invaluable talks by Prof C N Yang and the invited speakers reviewing these remarkable contributions and their importance for the future of physics.
