Introduction:

Researcher Guan Xiwen, after graduating from Jilin University in 1998 and doing postdoctoral research in Germany and Brazil from 2002 to 2002. From 2003 to 2012, he served as a researcher and senior researcher at the Institute of Physics and Engineering at the Australian National University. In October 2012, he was introduced to the Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences as an outstanding overseas talent. Senior visiting scholar at Harvard University, Los Alamos National Laboratory and other world-class research institutions, visiting professor at Tsinghua University Institute for Advanced Study, and visiting scholar Yang Zhenning at the Chinese University of Hong Kong. Chief expert of key projects of the National Natural Science Foundation of China and key special projects of the Ministry of Science and Technology. He is also a member of the Advisory Panel of Journal of Physics A. Researcher Guan Xiwen has long been engaged in rigorous solutions of cold atom few-body and many-body physical systems and spin systems, and has achieved a series of influential research results in the world. More than 110 SCI papers have been published so far, including the world's top journals "Review of Modern Physics", "Advance in Physics", "Nature Communications", "Physical Review Letters", etc.

Abstract:

It has long been appreciated that exactly solved mathematical models describing the statistical mechanics of interacting particles have played a key role in the developments of formerly unrelated areas of mathematics and theoretical physics, such as the study of quantum groups, combinatorics, conformal field theory, nuclear physics and condensed matter physics. However, over the past two decades striking experimental achievements in trapping and cooling atoms in one-dimensional (1D) optical waveguides have provided remarkable realisations of exactly solved models in the lab. In this talk, I will describe some of these fundamental mathematical models and their relevance to recent and future experiments on quantum liquids, quantum correlations and quantum criticality in 1D.
