High energy density matter, an extreme state of mater, in which the deposited energy is greater than 1011 J/m3 or the equivalent pressure is larger than 1 Mbar. The unique state of matter not only exists in the interior of a massive star, but also is an important process in inertial confinement fusion. The research on high energy density physics (HEDP) is of great significance in the development of traditional plasma physics, atomic physics and thermodynamics, and has potential application in the fields of astrophysics, new energy explorations and space technology.
The High Energy Density Physics Group focuses on experimental and theoretical investigations of high energy density physics driven by heavy ion beam based on accelerator facilities—HIRFL and HIAF. We are developing the crucial experimental technologies and plasma diagnostics, and realizing theoretical simulation by PIC and hydrodynamic methods. Fundamental properties of matter in unexplored regions, such as equation of state, exotic phase transition, transport and opacity, and strong inter-particle interaction will be investigated. We are establishing an international collaboration for HEDP driven by ion beam. Studies of laser spectroscopy of radioactive atoms at HIAF are also carried to expand the research fields of atomic physics and nuclear physics related to radioactive ion beam.
