Quantum field theory is the basis of our modern description of physical phenomena at the fundamental level. This systematic and comprehensive text emphasizes nonperturbative phenomena and supersymmetry. It includes a thorough discussion of various phases of gauge theories, extended objects and their quantization, and global supersymmetry from a modern perspective. This Second Edition is revised to include topics developed in the last decade, including higher-form global symmetries and their applications, anomalies in supersymmetric theories beyond Ferrara-Zumino, and non-Abelian supersymmetric vortex strings. A new final part is added, presenting more than 90 problems with detailed solutions, allowing students to check their understanding of the acquired knowledge and providing extra details to supplement the main text descriptions. This an indispensable book for graduate students and researchers in theoretical physics.

This book presents the first detailed biography of George Placzek — an outstanding physicist, a participant in the Manhattan Project who stood at the very inception of nuclear physics and the subsequent development of the nuclear bomb in the course of the WWII. In the 1930s, George Placzek was known as an adventurous person with a sharp sense of humor, a tireless generator of novel physics ideas which he generously shared with his colleagues. Born in Brno (now Czech Republic) into a wealthy Jewish family, he lost all his relatives to Holocaust, casting a tragic shadow on his life.Placzek's scientific career began in the late 1920s when the quantum revolution was almost over, but nuclear physics was still at its infancy. He established personal and scientific relations with the creators of quantum mechanics, such as Heisenberg in Leipzig and Niels Bohr in Copenhagen. In Rome, he worked with Fermi, and in Copenhagen he became a part of Bohr's nuclear physics team which dominated nuclear theory at that time. The scope of Placzek's pilgrimage around world physics centers in the 1930s was unique among his colleagues. In January 1939, George Placzek managed to emigrate from Europe to the US, and became a part of the British Mission within the Manhattan Project. His physical insights were instrumental in advancing from the basic discoveries on nuclear chain reactions to the Trinity experiment, Hiroshima and Nagasaki.This book is a unique compilation of a large number of previously unknown and unpublished documents from private and university archives, police reports, etc. Placzek's correspondence with the leadership of the Hebrew University in 1934, the 1937 NKVD interrogation files of Konrad Weisselberg, recollections of Ella Andriesse as well as the Zurich Police report of 1956 detailing the circumstances of Placzek's death in a Zurich hotel are illuminating as they shed light on poorly known pages of his life.

This textbook grew out of lecture notes the author used in delivering a quantum field theory (QFT) course for students (both in high energy physics and condensed matter) who already had an initial exposure to the subject.It begins with the path integral method of quantization presented in a systematic and clear-cut manner. Perturbation theory is generalized beyond tree level, to include radiative corrections (loops). Renormalization procedures and the Wilsonian renormalization group (RG flow) are discussed, asymptotic freedom of non-Abelian gauge theories is derived, and some applications in Quantum Chromodynamics (QCD) are considered, with a brief digression into the Standard Model (SM). The SM case requires a study of the spontaneous breaking of gauge symmetry, a phenomenon which would be more appropriate to call "Higgsing of the gauge bosons." Other regimes attainable in gauge theories are explained as well. In the condensed matter part, the Heisenberg and Ising model are discussed. The present textbook differs from many others in that it is relatively concise and, at the same time, teaches students to carry out actual calculations which they may encounter in QFT-related applications.

This invaluable collection of memoirs and reviews on scientific activities of the most prominent theoretical physicists belonging to the Landau School — Landau, Migdal, Zeldovich, Smorodinsky, Ter-Martirosyan, Kirzhnits, Gribov, Larkin and Anselm — are being published in English for the first time.The main goal is to acquaint readers with the life and work of outstanding Soviet physicists who, to a large extent, shaped theoretical physics in the 1950s–70s. Many intriguing details have remained unknown beyond the “Iron Curtain” which was dismantled only with the fall of the USSR.
