Description
In this book, Robert Wald provides a coherent, 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 will be accessible to students and researchers who have had introductory courses in general relativity and quantum field theory, and will be of interest to scientists in general relativity and related fields.

Reviews from Amazon users which were colected at the time this book was published on the website:
⭐I find this text very approachable and useful. If the presentation feels abstruse or the proofs incomplete, I would suggest reading Birrell and Davies first. Perhaps the two together? Wald is not intended to be a reiteration of Birrel and Davies, but rather a more abstract extension of it. Because QFT on a curved manifold is more about GR than about the intricacies of standard QFT, I believe that prerequisites require a general understanding of QFT in Minkowski Space and a more thorough understanding of GR.
⭐This is not a book but rather a well organized set of notes. As such, the author doesn’t go into much detail when a derivation is presented. One of the best features of the book is that it isn’t very expensive, so the lack of detail I mentioned before doesn’t feel that bad, especially since it contains many references which can be useful to fill in the blanks. There is only one thing that I didn’t like about this text: the typeset. The notes seem to be written in Word, making it cumbersome to read equations, and while their physical content is explained in words, this deal breaker made me award the notes only three stars.
⭐I had hoped this would be an affordable substitute for Birrell and Davies. Unfortunately, it is no substitute. The presentation is very sketchy and abstract. If you are into algebraic QFT and that sort of stuff then maybe you will like this book more than I did.
⭐its a great. Just what I was looking for and what I needed. Thank you very much for your efforts
⭐a great book
⭐Try another book that goes even deeper in only 30 pages.It’s called “Everything About Black Holes” and it explains everything with science. It’s on Amazon.
⭐Innovative well written
⭐Il testo è una introduzione ad alcuni argomenti specialistici della fisica teorica. L’autore, R. M. Wald, ha ottime capacità didattiche.Ho però dato solo tre stelle perché l’edizione è un po’ scadente: le formule sembrano scritte utilizzando l’equation editor di Word:Dato il prezzo non proprio economico, mi sarei aspettato un’edizione per lo meno scritta utilizzando LaTeX, se non in modo più professionale. Invece sembra una copia anastatica delle dispense di un corso.Capisco che si tratti di un testo con una limitata circolazione, ma di certo la qualità della stampa non aiuta.Lectura imprescindible para conocer una consteucción general de la teoría para campos cuánticos no interactuantes en geometrías de espacio-tiempo curvas. Discute conceptos que surgen por la no invariancia bajo el grupo de Poincaré como la no definición de partícula. Un libro imprescindible para cualquier físico teórico.詳しく計算を追うというスタイルではなく、文が大半を占めている。読みやすいので読み物として買うとよい。但し、フォント及び数式が読みずらい(TEX調ではない)ので気にする人は注意。
