Computation and Quantum Simulation of Many-body Systems

Principal investigator
Introduction

We aim to develop efficient numerical techniques and cold-atom quantum simulation methods, and explore emergent macroscopic properties of many-body systems, particularly including phase transitions and critical phenomena. Our research activities mainly include:
Monte Carlo Methods
Phase Transitions and Critical Phenomena
Quantum Simulation Theory
