Computing Optical Conductivities of Warm Dense Matter with Time-Dependent Density Functional Theory

In magnetized liner inertial fusion (MagLIF), matter is subjected to 10-30 T magnetic fields that are then flux compressed to strengths greater than 1 kT [Slutz et al, Phys. Rev. Lett. 108, 025003 (2012)]. The determination of optical and transport properties for warm dense matter in such extreme fields is of vital importance to experimental design. We show how time-dependent density functional theory can be used to extract optical conductivities in and beyond the linear response regime. Building on work studying scalar linear perturbations to warm dense matter [Baczewski et al., Phys. Rev. Lett. 116, 115004 (2016)], we present the necessary theoretical modifications as well as some preliminary results.
