• Experiments on SrCu₂(BO₃)₂
  

个人简介

Prof. Sandvik completed his M.Sc. at Åbo Akademi University in Finland and his Ph.D. at the University of California, Santa Barbara, in 1993. He carried out postdoctoral work at Florida State University, the University of Illinois at Urbana-Champaign, and Los Alamos National Laboratory, before returning to Finland as a Senior Fellow of the Academy of Finland in 2000. He joined the Boston University as an Associate Professor of Physics in 2004 and was promoted to Full Professor in 2008. In 2018 he joined the Institute of Physics of the Chinese Academy of Sciences as a Distinguished Professor. He has published more than 100 research articles on computational algorithms and their applications to condensed-matter systems at the electronic level. In recognition of his work on quantum magnetism, he was elected a Fellow of the American Physical Society in 2007. His recent research has been focused on quantum phase transitions beyond the standard paradigms.

会议简介

This workshop will focus on recent advances in the field of quantum many-body computation, including Monte Carlo methods, renormalization group and tensor network methods, machine learning, etc. It aims to provide young researchers and graduate students with introductory and updated research information, promote exchange of ideas and in-depth discussions, and enhance the interactions of researchers working in relevant areas.
