Title: Quantum simulation of far-from-equilibrium gauge-theory dynamics

Abstract: 

Gauge theories are a fundamental framework of modern physics and the staple of the Standard Model. Their principal property, gauge symmetry, implements the laws of nature through intrinsic local relations between matter and gauge fields, with Gauss’s law from electrodynamics as a paradigmatic example. In recent years, there has been a considerable drive in realizing gauge theories on quantum simulators, which are accessible tunable tabletop devices that can naturally handle entanglement buildup owing to quantum advantage. In this talk, I will first motivate this technology and then discuss recent theoretical and experimental progress in quantum simulators of 1+1D Abelian gauge theories in cold-atom platforms. I will then discuss a plethora of exotic far-from-equilibrium phenomena that one can probe on such quantum simulators. I will end by discussing experimental proposals toward advancing quantum simulators of gauge theories to higher spatial dimensions, non-Abelian gauge groups, and towards the lattice quantum field theory limit.

About the Speaker:

After finishing my PhD in theoretical physics at LMU Munich in January 2017, I joined the Max Planck Institute for the Physics of Complex Systems in Dresden for 2 years as a postdoc, then moved to the University of Trento as a postdoc for 2.5 years, before joining my current position at LMU Munich as a postdoc in January 2022. In January 2024, I will head my own research group at LMU Munich.
