SUMMARY:CM Seminar: Professor Romain Vasseur - Anomalous Diffusion in Quantum Spin Chains
DESCRIPTION:Professor Romain Vasseur – University of Massachusetts\, Amherst \nTitle: Anomalous diffusion in quantum spin chains  \nAbstract: High-temperature quantum transport is usually assumed to be incoherent and diffusive.  In this talk\, I will explain how anomalous transport in quantum spin chains can emerge from proximity to special integrable limits\, due to a hierarchy of long-lived quasiparticle excitations. I will summarize our understanding of finite-temperature transport in integrable spin chains\, and argue that integrability-breaking perturbations can generically lead to either super- or subdiffusion up to very long-time scales. \nBio: Romain Vasseur is an Associate Professor in the Physics Department of the University of Massachusetts\, Amherst.  He is a condensed matter theorist working on strongly correlated quantum systems and quantum information\, with a focus on the interplay of strong interactions and quantum entanglement\, leading to new emergent phenomena both in thermal equilibrium and in non-equilibrium quantum systems. Before moving to Amherst\, Dr. Vasseur was a Postdoctoral Fellow at Lawrence Berkeley National laboratory (2013-2017)\, working in the Condensed Matter Theory Center at the University of California\, Berkeley. He obtained his PhD at IPhT (CEA\, Saclay) and LPTENS (ENS\, Paris) in 2013. Prof. Vasseur has been recognized as a fellow of the Alfred P. Sloan Foundation (2019) and an Early Career Award of the US Department of Energy (2018). He is also the recipient of a Young Investigator Award of the US Air Force Office of Scientific Research (2020). \n
