Self-Consistent Radiative Scattering in Time Dependent Density Functional Theory

Time Dependent Density Functional Theory (TDDFT) is an ab initio theory that can be used to model time varying electron densities. We propose a semi-classical method for calculating the self-consistent radiation from a time varying electron density in a TDDFT framework. This scheme allows one to simulate a system where a time varying electron density scatters energy both into the lattice as well as into an electro-magnetic field. We will present a description of this technique and describe a few applications in which it has been employed.
