Title: Quantum Spin Chains and Topology

Timings: 18th March, Mon 5-7pm; 20th March, Wed 5:30-7:30pm

He will give a set of pedagogical lectures on quantum condensed matter theory, and I invite you to attend them. Below is a short description of the lectures:

In this set of lectures, I will introduce the simplest quantum many-body problems, quantum spin chains. The physics that spin chains host is diverse and profound and covers a large number of exciting topics in contemporary theoretical physics, including the powerful role of topology in statistical mechanics. The lectures will explain some of the discoveries that were recognized in the 2016 physics Nobel prize.

Topics:
Classical Ising model
Quantum-Classical mapping
Transverse field Ising model.
XY Chain
Topological Terms
Spin Coherent Path Integrals
Heisenberg Chain & Haldane’s theta term
Quantum critical points
 

Short Biography: Prof. Kaul did his Ph. D. at Duke University, followed by postdoctoral positions and Harvard University and Microsoft Station Q (University of California, Santa Barbara). He is a leading theorist on quantum magnetism and phase transitions, computational approaches to condensed matter. His website: http://www.pa.uky.edu/~rkk/index.html
