Introduction of Distinguished JCAS Speaker Prof. Lu J. Sham

Professor Sham is a prominent physicist, born in Hong Kong. He was graduated from the Pui Ching Middle School and then traveled to England for his higher education. He got his B.Sc. in Mathematics from Imperial College, University of London in 1960 and Ph.D. in Physics from University of Cambridge in 1963. In 1963-66, he worked with Professor W. Kohn as a postdoctoral fellow in University of California, San Diego. Since 1968, he has been in the faculty of UCSD and currently he is the Distinguished Professor of Physics and Adjunct Professor in Electrical and Computer Engineering. Professor Sham is a founder (together with W. Kohn and P. Hohenberg) of the density functional theory which lays a foundation of modern quantum chemistry and computational physics. The 1965 paper presenting the Kohn-Sham theorem [Physical Review, Volume 140, page A1133] was the very most cited Physical Review paper up to 2003 according to Physics Today’s report (S. Redner, page 49, May issue, 2005). Professor Sham has many other important contributions to condensed matter physics including many-electron theory, exciton dynamics, phonon dynamics, and nonlinear and quantum optical properties of solids. For his distinguished achievements, he has been elected to U.S. National Academy of Sciences (Member), Academia Sinica (Member), and American Physical Society (Fellow) and been awarded W. E. Lamb medal for Laser Science and Quantum Optics (2004) among many other honors. Professor Sham is still very active and productive in research, especially in spin-based electronics and quantum information science. He is running several large-scale projects and working with leading experimentalists like D. D. Awschalom in UCSB and D. G. Steel in U. Michigan, for the generation of quantum technologies. Professor Sham is visiting the CUHK, HKUST, and HKU as the Distinguished JCAS (Joint Centre for Advanced Study) Speaker from 25 September through 24 October and will deliver a series of lectures on some fundamental issues of future quantum technologies. He would also like to interact with local researchers and students during this visit and beyond.
