Prof. Xuzong Chen was born at Suzhou City, Jiangsu Province in April, 1958.He received PhD degree in Shanghai Institute of Optics and Fine Mechanics, Chinese Science Academy, in 1993. He was a postdoctor in Department of Electronics, Peking University from 1993 to 1995.He was an associate professor of Peking University from 1995,and was a professor of Department of Electronics, Peking University from 2000. He was a fellow researcher in AIST at Japan from 1996 to 1997, and a visiting professor at Heidelberg University, Provence University, Ecole Normale Supérieure, etc.from 2003 to 2007.From 1993 he joined Prof.Yiqiu Wang’s group and began to establish the Laser Cooling and Trapping Lab. in Peking University with the group members. In 1996, he achieved the first MOT in china with his colleagues, and from 1998, he led a group to start the research of semiconductor laser frequency standard at 630 to 640nm. From 2001, he became the leader of CAP group (Cold Atom and Precision Measurement), his group achieved BEC in March, 2004 and achieved atom laser of Rubidium in Jan. 2005 respectively. His group also achieved some interesting results in controllable internal states transition of BEC by Majorana transition(2006), controllable quantum momentum transition of mater wave with superradiant scattering (2007), Phase transition from superfluid to number states of one dimensional optical lattices (2009) etc. From 2002 his group started experiments of slow light and light storage in EIT medium and from 2003 he started building up femtosecond laser comb generator for precision measurement. His group developed several novel methods in absolute frequency measurement of iodine molecular hyperfine transition and alkali atomic hyperfine transition. Recently he is involving cold atom physics, diode laser frequency standard, precision measurement based on phase locked femtosecond laser and optical pumped atomic clock. Up to now, he published over 100 papers in journals. He is a fellow of IOP, UK, and a fellow of Quantum Optics Division, Chinese Association of Physics and a fellow of Chinese Association of Metrology and Measurement.
