Biography：Dr. Yidun Wan is a tenured professor of physics at Fudan University. He has a diverse educational background, with bachelor’s degrees in computer science and economics from the South China University of Technology (1998), Master of Computer Science from the University of Pennsylvania (2002), Master of Physics from the University of Ottawa (2004), and PhD in theoretical physics from the University of Waterloo and Perimeter Institute for Theoretical Physics (2009). He also did postdoctoral research at Kinki University, Tokyo University, and Perimeter Institute for Theoretical Physics from 2009 to 2016. He joined Fudan as a professor in 2016. His research interests include topological phases, quantum information and computation, and cosmology.
Title：Anyon Condensation as a Higgs Mechanism
Abstract：Topologically ordered matter phases have been regarded as beyond the Landau-Ginzburg symmetry breaking classification of matter phases. Recent studies of anyon condensation in topological phases, generalizing the notion of boson condensation, however, may fit topological phases back in the Landau-Ginzburg paradigm expanded to include discrete symmetry breaking. To illustrate this new understanding, in this talk, I shall offer a precise comparison between the mechanism of and phenomena caused by anyon condensation to/with the usual higgs mechanism and phenomena in superconductors and electroweak theory.
