Robert M. Wald – författare

In this book, Robert Wald provides a pedagogical introduction to the formulation of quantum field theory in curved spacetime. He begins with a treatment of the ordinary one-dimensional quantum harmonic oscillator, progresses through the construction of quantum field theory in flat spacetime to possible constructions of quantum field theory in curved spacetime, and, ultimately, to an algebraic formulation of the theory. In his presentation, Wald disentangles essential features of the theory from inessential ones (such as a particle interpretation) and clarifies relationships between various approaches to the formulation of the theory. He also provides a comprehensive, up-to-date account of the Unruh effect, the Hawking effect, and some of its ramifications. In particular, the subject of black hole thermodynamics, which remains an active area of research, is treated in depth. This book is intended for students and researchers who have had introductory courses in general relativity and quantum field theory, and should be of interest to scientists in general relativity and related fields.

Writing for the general reader or student, Wald has completely revised and updated this highly regarded work to include recent developments in black hole physics and cosmology. Nature called the first edition "a very readable and accurate account of modern relativity physics for the layman within the unavoidable constraint of almost no mathematics. . . . A well written, entertaining and authoritative book."

"Wald's book is clearly the first textbook on general relativity with a totally modern point of view; and it succeeds very well where others are only partially successful. The book includes full discussions of many problems of current interest which are not treated in any extant book, and all these matters are considered with perception and understanding."—S. Chandrasekhar "A tour de force: lucid, straightforward, mathematically rigorous, exacting in the analysis of the theory in its physical aspect."—L. P. Hughston, Times Higher Education Supplement"Truly excellent. . . . A sophisticated text of manageable size that will probably be read by every student of relativity, astrophysics, and field theory for years to come."—James W. York, Physics Today

The inevitability of gravitational collapse for stellar bodies of sufficient mass was convincingly demonstarted by S. Chandrasekhar in the 1930s, black holes and neutron stars played a minor role in serious analyses of physical or astrophysical phenomena until the discovery of quasars and pulsars in the 1960s. Black holes and neutron stars are now generally recognized as key components of many astrophysical systems, and play a central role in the understanding of gravitational phenomena at both the classical and quantum levels. Based on a symposium held in honour of S. Chandrasekhar, these papers provide a comprehensive summary of progress made in the 1990s on the theory of black holes and relativistic stars.
