The equation of state, transport coefficient and multicomponent mixing property of deuterium-tritium plasma in the high density regime are of crucial interest for plasma physics, astrophysics, and intense ion-beam, electron-beam or high-power laser interaction with matter. The present project will perform theoretical modeling and numerical simulation on the thermophysical properties for the dense deuterium-tritium plasma with dopants in many aspects, including: To realize the modeling technology for thermophysical properties of material under high density and high temperature, we intent to build short cutoff radius atomic pseudopotentials, introduce and develop orbital free molecular dynamic simulation code; By using quantum molecular dynamic simulation, the equation of state for dense deuterium-tritium plasma can be obtained. The atomic transport coefficient, the electronic transport coefficient and radiation thermal conductivity of the dense plasma will be modeled through a self-consistent method, meanwhile, the process on the transport, as well as the conversion of energy will be discussed; Quantum effect of the ionic coupling and electronic degeneration are planned to be expatiated; We also focus on the mixing properties, structure transition, and pressure induced ionization of plasma with dopant. The present work will improve the experimental and theoretical progress in high energy density physics.
