Abstract

Empirical tight-binding theory is generalized to incorporate time-dependent electromagnetic fields in a systematic and gauge-invariant manner that does not introduce any extra adjustable parameters. It is shown that this approach successfully predicts a wide range of solid state properties that have not been accessible within the tight binding method so far. We present applications such as optical constants, luminescence in heterostructures, properties in ultra-high magnetic fields and lattice dynamics in polar materials.
