报告简介：
Energy band structures due to energylevel broadening and merging caused by the selfenergy shift from the compression effect of matter in the warm dense Al are found, and a number of electrons from pressure ionization, which are in Mott scattering states and result in a significant electric (thermal) transport, are observed by numerical simulations. We proposed an energy band theory for warm dense matter (WDM), which involves the scattering wave, the plane wave and the degenerate atom with significant boundenergylevel shifting and broadening, and developed an extended QMD (EQMD) method under the frame of thermal density functional theory. Using EQMD, with the great reduction of computing time, we have numerically accomplished a large account of data related to equation of state, electrical (thermal) conductivities, etc., in which all embody clear electronicstructure features, and for the first time we also investigate the partial degenerate boundaries for WDM using Lorentz number.
报告人介绍：
Prof. He is theoretical physicist, graduated from the Department of Physics, Zhejiang University, in 1962. Research professor, supervisor for Ph.D. student, and the former deputy director of Institute of Applied Physics and Computational Mathematics (IAPCM) in Beijing. Now he is chief scientist of National 863 HiTech Inertial Confinement Fusion (ICF) Project and chief scientist of IAPCM; Member of Expert Committee of Nonlinear Science, Major State Basic Research. He made important contributions to theoretical research on physics of nuclear weapons. In the field of plasma physics, he first obtained an exact expression for spontaneously magnetic field generated from electromagnetic wave interaction; and first derived the cubicquintic Schrodinger equation and its solitary wave solution. And he also achieved many original fruits, such as found mechanism for solitary waves to accelerate particles, coherent turbulence with smallscale correlation in plasma, etc. He was awarded the Second Prize of National Nature Science, the First and Second Prizes of National Science and Technology Advances, and other Ministry Prizes etc. He was elected Member of Chinese Academy of Sciences in 1995.
