Pan Jianwei, Professor, University of Science and Technology of China: Progress in One-Dimensional Quantum Liquid Research

Pan Jianwei, a professor of China University of Science and Technology and his colleague Yuan Chun-sheng, cooperated with Guan Xiwen, a researcher at Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences. Through the quantum control and measurement of ultra-cold atoms in optical lattices and the combination of quantum integrable system theory , For the first time in the world, the quantum criticality of a one-dimensional finite temperature multi-body system transitioning between classical gases and quantum liquids has been obtained and the power law correlation characteristic of Lanting jie liquid has been observed by measuring its phase correlation. Progress in multi-body system research. The research results recently published in the Physical Review Letters, and was elected editor of the recommended article. GIAmarchi, a professor at the University of Geneva in the field of physics, invited by the Physics Society of the United States, commented on the research results under the theme of "One-Dimensional Quantum Material Theory Validated in Cold Atoms and Superconductors." Physicsworld, a site of the European Institute of Physics, reports on the results of simulating one-dimensional quantum liquids with atomic systems and Josephsonian nodes.
