Conference and Workshop

2006.07.26

Date	July 26, 2006 (Wed)
Time	9:30 a.m. - 5:30 p.m.
Venue	Lecture Theatre T3, Meng Wah Complex, HKU
Key Speaker	Prof. Xiao-Gang Wen at MIT Prof. Naoto Nagaosa at Tokyo University

Jointly organized by Centre of Theoretical and Computational Physics and Department of Physics, HKU; Department of Physics, HKUST; and Physical Society of Hong Kong

Xiao-Gang Wen and Naoto Nagaosa are among the most distinguished and active physicists in their generation. They will be visiting Hong Kong as distinguished visitors jointly sponsored by HKUST and HKU. We would like to use this opportunity to organize a miniworkshop to introduce their recent researches. There will also be a talk given by Prof. Pengcheng Dai from Oak Ridge Lab. and Univ. of Tennessee, as well as several short talks from local physicists.
