报告摘要：Free fermions are not correlated systems but are still a very nontrivial platform for the quantum entanglement perspective. In this talk, I will present how entanglement entropy scales when non-interacting (free) fermions of finite density hop on various lattices. Several remarkable results beyond the traditional Klich-Gioev-Widom scaling are identified, reflecting a rich landscape induced by the interplay of entanglement, locality, and fermionic statistics.
Peng Ye is currently a professor at Sun Yat-sen University (since August 2018), working in the field of quantum many-body theory. He earned his B.Sc. in Physics from Sun Yat-sen University in July 2007 and completed his PhD at the Institute for Advanced Study of Tsinghua University in July 2012. From September 2012 to August 2015, he worked as a postdoctoral researcher at the Perimeter Institute for Theoretical Physics in Canada. He then became a postdoctoral research associate and Gordon & Betty Moore fellow at of the Anthony J. Leggett Institute for Condensed Matter Theory and Department of Physics at the University of Illinois at Urbana-Champaign, USA, from August 2015 to August 2018.
