Quantum Field Theory

The rise of quantum electrodynamics (QED) made possible a number of excellent textbooks on quantum field theory in the 1960s. However, the rise of quantum chromodynamics (QCD) and the Standard Model has made it urgent to have a fully modern textbook for the 1990s and beyond.

Over the past few decades the powerful methods of statistical physics and Euclidean quantum field theory have moved closer together, with common tools based on the use of path integrals. The interpretation of Euclidean field theories as particular systems of statistical physics has opened up new avenues for understanding strongly coupled quantum systems or quantum field theories at zero or finite temperatures.

Authors: Padmanabhan, Thanu
A refreshingly new approach to developing and teaching QFT
Author is a leading theoretical physicist, known too for his excellent writing and teaching
A slim volume but covering all the main concepts and calculational prerequisites
Problems interspersed in the text help to give the student a deep understanding in confidence in using QFT
Interesting applications beyond standard calculations show the broad range of applicability of these methods

The ancient Greeks believed that everything in the Universe should be describable in terms of geometry. This thesis takes several steps towards realising this goal by introducing geometric descriptions of systems such as quantum gravity, fermionic particles and the origins of the Universe itself.
