[PDF] Path integral approach to quantum physics: an introduction G. Roepstorff

The present text is designed to introduce graduate students to the functional integration method in contemporary physics as painlessly as possible. The author concentrates on the conceptual problems inherent in the path integral formalism. The striking interplay between stochastic processes, statistical physics and quantum mechanics comes to the fore. The reader will find all the methods of fundamental interest amply illustrated by important physical examples.
