MOTT TRANSITIONS AND ANOMALOUS QUANTUM PHASES IN CORRELATED ELECTRON SYSTEMS

在这项研究中，我们澄清了在强相关系统中出现的莫特转变附近的各种异常现象。我们不仅研究了电子系统，而且研究了近年来被广泛研究的冷原子系统。特别地，我们阐明了多轨道和受挫系统中的Mott跃迁，冷费米系统中的量子相变和猝灭动力学，玻色-费米混合物中的一种新型多体效应等。

In this research, we have clarified a variety of anomalous phenomena that emerge near the Mott transition in strongly correlated systems. We have studied not only electron systems but also cold atom systems which have been studied extensively in recent years. In particular, we have elucidated the Mott transitions in multiorbital and frustrated systems, quantum phase transitions and quench dynamics in cold Fermi systems, a new type of many-body effect in a Bose-Fermi mixture, etc.
