Overview
Kálmán Varga works on time-dependent simulations of the interaction of light
and matter. The matter (electrons and
nuclei) are described quantum mechanically and the light is described either with the
quantized or the classical Maxwell equations. The light and the matter are
coupled, the electromagnetic fields
excite the matter and the electron and nuclear dynamics induce electromagnetic
fields.
