Overview

Traditionally, field theory is taught through canonical quantization with a heavy emphasis on high energy physics. However, the techniques of field theory are applicable as well and are extensively used in various other areas of physics such as condensed matter, nuclear physics and statistical mechanics. The path integral approach brings out this feature most clearly. In this book, the path integral approach is developed in detail completely within the context of quantum mechanics. Subsequently, it is applied to various areas of physics.Contents: IntroductionPath Integrals and Quantum MechanicsHarmonic OscillatorGenerating FunctionalPath Integrals for FermionsSupersymmetrySemi-Classical MethodsPath Integral for the Double WellPath Integral for Relativistic TheoriesEffective ActionInvariances and Their ConsequencesSystems at Finite TemperatureIsing ModelReadership: Mathematical physicists and high energy physicists.
