Abstract:     

　　Topological orders characterized by long-range quantum entanglement can emerge either from frustrated quantum magnets or correlated fermions. Typical examples include the fractional quantum Hall states and the quantum spin liquids, which have been extensively studied over the last decades. In this talk, I will give an overview of my recent studies. Some different understandings will be introduced on quantum magnetism, quantum spin liquids, as well as the phase transition between them. I will also propose a possible indicator for chiral topological order for interacting fermion systems.

　　Rui Wang received Ph.D. in Physics from Nanjing University in 2017.He then worked as a post doctor in Shanghai Jiao Tong University till 2019. He joined Nanjing University as a research fellow in 2019 and became an associate professor in 2021. His research interest mainly involves the strongly correlated systems, particularly novel quantum phenomena driven by both correlation and topology. His published works involve several related fields, including quantum magnetism, quantum spin liquids, Kondo phenomena in topological baths.
