"The Cluster Truncated Wigner Approximation in Strongly Interacting Quantum Systems"

Speaker: Jonathan Wurtz, Boston University, Department of Physics

When: December 8, 2017 (Fri), 12:00PM to 01:00PM (add to my calendar)
Location: SCI 352

This event is part of the Condensed Matter Theory Seminar Series.

Quantum many-body systems exhibit a rich set of interesting behavior, from many body localization to thermalization. However, existing methods are lacking a way to describe generic out-of-equilibrium dynamics of such systems, mainly due to the exponential complexity of large systems. In this seminar, I describe work done on describing non-equilibrium dynamics of strongly interacting quantum systems from the perspective of phase space. Within this perspective, linear quantum dynamics with exponential DoF is replaced with approximate nonlinear classical dynamics with polynomial DoF. I will also describe some results and behavior of the method, including entanglement growth and spreading, and the change between quantum and classical behavior.
