# Path Integrals in Quantum Physics

@article{Rosenfelder2012PathII, title={Path Integrals in Quantum Physics}, author={R. Rosenfelder}, journal={arXiv: Nuclear Theory}, year={2012} }

These lectures aim at giving graduate students an introduction to and a working knowledge of path integral methods in a wide variety of fields in physics. Consequently, the lecture notes are organized in three main parts dealing with non-relativistic quantum mechanics, many-body physics and field theory. In the first part the basic concepts of path integrals are developed in the usual heuristic, non-mathematical way followed by the standard examples of quadratic Lagrangians for which the path…
