Title: Numerical studies of the quantum simulation based on Rydberg array

Speaker: Prof. Zheng Yan (Westlake University)

Time: Dec. 27 (Wednesday), 10:00

Place: Rm M830, IOP-CAS

Abstract:

Due to local constraints induced by Rydberg blockade, novel physics of lattice gauge theory can be widely simulated and has attracted a lot of attentions and discussions in the related scientific communities. In this talk, I will introduce several fresh works by us in this area along two main branches: 1. The emergent novel phases in Rydberg arrays: odd/even Z2 spin liquids, a hidden order disguised as a spin liquid, emergent glassy phase. 2. New challenges in gauge field simulations and the solutions: how to prepare target states among topological sectors.
