报告摘要:Understanding strongly correlated electrons is an important long-term goal, not only for uncovering fundamental physics behind, but also for their emergence of lots of novel states which are potentially being used in quantum control and quantum computations. Meanwhile, the strongly correlated electrons are usually extremely hard problems, especially for a complete unbiased understanding. In this talk, I will summarize our efforts on unbiased numeric understanding of several novel phases and phase transitions, such as gapless quantum spin liquids, the itinerant quantum criticality, the competition between unconventional superconductivity and magnetism, as well as the recent found correlated phases and phase transitions in moiré quantum matter.
