Numerical simulations of fundamental light-matter interactions.

Abstract

We present the results of the numerical investigations of light-matter interactions in one and two dimensions from the quantum mechanical perspective. We investigate the dynamics of two-level systems coupled to quantized electromagnetic fields. We construct a quantum mechanical model to demonstrate how light interacts with classical objects such as mirrors and beam-splitters made from group of atoms, where each atom is modelled as a two-level system. We have been able to simulate behaviour of a singlephoton being reflected and transmitted as a process of absorption and re-emission by the atoms.
