“Many-Body Physics in Long-Range Interacting Quantum Systems”
Abstract: Condensed matter systems often have short-range interactions, and this locality of interactions has profound effects on the properties of both ground states and states created out of equilibrium. However, in numerous systems of current interest, ranging from frustrated magnets, spin glasses, and low-dimensional materials to various atomic, molecular, and optical systems, long-range interactions are ubiquitous and can lead to qualitatively new physics. In this talk, I will review our recent work on how long-range interactions can give rise to novel dynamical behaviors, exotic quantum phases, and significant speedups in quantum information processing. In particular, I will introduce the notion of emergent locality, which is crucial in understanding a wide range of many-body physics in long-range interacting quantum systems.
