An Optical Lattice with Sound - Benjamin Lev

Explore the innovative concept of an optical lattice created with sound in this 45-minute conference talk from the 2021 Non-Equilibrium Universality in Many-Body Physics KITP Conference. Delve into the world of quantum simulators and their impact on non-equilibrium many-body physics as Benjamin Lev discusses traditional optical lattices, mode spectrum, and the confocal cavity. Examine momentum exchange, translational symmetry, and the vacuum chamber setup. Learn about spatial heterodyne techniques and super radiant phase transitions. Investigate double pump systems, roton and phonon dispersions, and their implications. Engage with thought-provoking questions on controlled system manipulation, the role of dissipation, and qualitative differences in thermal phase transitions. Gain insights into cutting-edge research at the intersection of statistical physics, AMO, condensed matter, and high-energy physics, exploring novel phases of matter far from equilibrium and their associated universality classes.
