In order to investigate quantum many-body problems beyond classical computational capability,artificial quantum systems have been developed to simulate the evolution of target Hamiltonians,referred as quantum simulation.Optical lattices of ultracold atoms are a widely-used platform for quantum simulation,which has realized various exotic quantum matters.However,the quantum control inevitably induces heating.In order to address this issue,a room-temperature quantum simulation platform was proposed and realized based on momentum-space superradiance lattices.This paper reports the recent progress on superradiance lattices,including the observation of chiral edge currents,flat-band localization,and dynamical localization and delocalization.Based on superradiance lattices,a spectroscopic method is presented to measure the geometric phases of topological matter,and various optical devices such as the optical diode can be designed.Superradiance lattices provide new approaches to quantum metrology and quantum simulation.
