Talk Title: "Quench dynamics in confined 1+1-dimensional systems"


I will present a new approach for analytically investigating the post-quench dynamics of confined 1+1-dimensional systems. Certain types of such systems have been shown not to thermalize after a quench, and I will explain how the absence of thermalization follows from this CFT-based approach. I will demonstrate the validity of this framework and its usefulness for realistic systems by modeling the split-momentum quench of the Kinoshita, Wenger, and Weiss [Nature 440, 900 (2006)] experiment and obtaining qualitative agreement with the experimental results. This agreement calls attention to the connections between integrability and conformal field theory and the extent to which a system whose post-quench dynamics are near-integrable may be analyzed by an application of boundary CFT techniques.
