Presently we are witnessing dramatic progress in experiments with dense quantum plasmas where matter is being compressed to densities exceeding solid density - parameters that occur in many astrophysical plasmas (planet interiors, dwarf stars etc.). At the same time, accurate laser and x-ray based diagnostic tools have emerged that probe the properties of such “warm dense matter”. To understand these experiments and predict new ones poses a challenge to theory and simulations [1] and requires a smart combination of different methods including density functional theory, generalized quantum hydrodynamics (QHD), quantum kinetic equations [2], and quantum Monte Carlo [3]. The talk gives an overview on recent developments.
