The chromatic flying focus, shown here, uses chromatic focusing and chirp to control the focal location and time of each frequency.
Accurate density functional theory simulations of warm dense matter require accurate exchange-correlation functionals with explicit temperature dependence. The simplest local-density approximations can handle homogeneous electronic landscapes, but higher-level functionals (meta-GGAs) are needed for more complex systems. fTSCAN is highly accurate across experimentally relevant densities and temperatures.
