Cambridge University Press Cambridge Introduction to Quantum Effects in Gravity Textbook

Master the fundamentals of quantum field theory in gravitational backgrounds with this essential textbook from Cambridge University Press. Designed specifically for undergraduate and beginning graduate students, this book provides a clear path into the complex realms of theoretical astrophysics, cosmology, particle physics, and string theory. This resource covers the necessary material for understanding the quantization of fields in an expanding universe and explores quantum fluctuations within inflationary spacetime. Readers will gain a detailed understanding of the Casimir, Unruh, and Hawking effects, which are fundamental to modern physics. Beyond basic concepts, the text introduces the method of effective action, a vital tool for calculating the back-reaction of quantum effects. Whether you are studying the early universe or the behavior of particles in curved spacetime, this textbook serves as a foundational guide for your academic journey in theoretical physics.
