Dr. Richard Eager,
Prof. J. Walcher,


Supersymmetric quantum mechanics stands at the beginning of much of the interaction between geometry/topology and quantum field/string theory in the past 25 years. It first led to a re-interpretation of classical Morse theory, and later inspired the development of Floer theory and the Fukaya category as prototypes of systems with an infinite number of degrees of freedom. Recent years have seen a resurgence of interest and progress in foundational aspects of the subject, including the calculation of supersymmetric indices by localization, and the complexification of parameter space.

This seminar aims to trace supersymmetric quantum mechanics from its beginnings in papers by E. Witten from the early 1980s to three select cutting edge developments:

In addition to recent excitement, a thorough understanding of supersymmetric quantum mechanics provides an easy gateway to many other contemporary topics in mathematical physics.

Prerequisites: The seminar is aimed at Masters students and advanced Bachelor students of mathematics and physics. The early parts should be accessible with a good knowledge of undergraduate quantum mechanics of finite-dimensional systems and basic notions of differential geometry. The level of the latter parts will be adjusted to the participants' background.
