Project Title: New understanding of liquid and supercritical states of matter
It is an interesting fact that the liquid state has proven to be difficult to describe by theory in comparison to solids and gases. In this project, we use theoretical method and molecular dynamics simulation to study both liquid and supercritical fluids. We consider liquid as solid below the Frenkel line. We introduce the phonon theory to describe the thermodynamic properties and study their relationship to dynamics and structure.
Another part of this project is to research the collective modes and their evolution with pressure and temperature in liquid and supercritical fluids. We study the recently discovered phonon gap in the reciprocal space by performing neutron and inelastic X-ray scattering experiments. We also look at the collective excitations at extreme supercritical conditions by simulation.
