报告摘要:
With the advancement of quantum technologies, increasing attention has been paid to the various effects induced by environmental decoherence in many-body systems. In this work, we develop several quantum Monte Carlo methods to investigate phenomena such as strong-to-weak symmetry breaking and novel phase transitions in decohered quantum many-body systems. These phenomena cannot emerge in closed systems, and their underlying mechanisms certainly require further understanding and exploration.
