A numerical approach is presented which allows to calculate the equilibrium properties of Coulomb systems which are both, strongly coupled and strongly degenerate. This is of particular interest for dense quantum plasmas in astrophysics or in inertial confinement fusion setups.
Based on a novel path integral representation [1,2] of the many-particle density operator, quantum and spin effects are included without additional approximations for the density matrix. As an illustration, results for the pressure and energy of an electron–proton plasma are presented.
