报告摘要：

The functional renormalization group (fRG) is a nonperturbative continuum field approach, in which quantum, thermal and density fluctuations are integrated in successively with the evolution of the RG scale. In this talk, I would like to discuss recent progress in fRG studies of QCD phase transitions at finite temperature and densities, including the QCD phase structure and the location of the critical end point (CEP), baryon number fluctuations and the ripples of CEP, the criticality of QCD phase transition, the moat regime in QCD etc. In particular, I would like to discuss the possibility and prospect to pin down the location of CEP with the ripples of CEP encoded in the baryon number fluctuations.

个人简介：

Wei-jie Fu is a professor of physics at Dalian University of Technology. He obtained Ph.D. in 2009 from Peking University. He held postdoctoral positions at Institute of Theoretical Physics, Chinese Academy of Sciences, Brandon University in Canada, and Institute for Theoretical Physics, University Heidelberg in Germany, before joining the Physics School of Dalian University of Technology as a faculty in 2016. His recent research interest focuses on the functional renormalization group approach and its application in the studies of QCD phase structure, QCD critical end point, heavy ion collisions, etc.
