Toward predictive modeling of Inertial Confinement Fusion plasmas — •Michael Bonitz, Daniels Krimans, Hanno Kählert, and Christopher Makait — Institute of Theoretical Physics and Astrophysics, Christian-Albrechts-Universität zu Kiel, 24098 Kiel, Germany

In Inertial confinement fusion (ICF) hydrogen rapidly undergoes compression, heating and ionization. Simulations have to take into account simultaneously laser-matter interaction, shock propagation, and nuclear reactions. Moreover, the initial phase of the compression is strongly influenced by nonequilibrium carriers, electronic quantum effects, and Coulomb correlations. Despite the rapid recent progress in theory and simulation of dense plasmas and warm dense matter [1], presently, no method exists that reliably captures all these processes, and commonly used radiation-hydrodynamics simulations do not have predictive capability. In Ref. 2 a solution of this dilemma has been proposed: a smart combination of a variety of different simulations, together with a first-principles based downfolding approach. The starting point are quantum Monte Carlo simulations, in equilibrium [3], and quantum kinetic theory [4], in nonequilibrium. This should allow for predictive ICF simulations in the near future.
