Time dependent Stark ladders: Exact propagator and caustic control
arXiv:1302.4008 · doi:10.1088/1751-8113/46/13/135302
Abstract
In this note we present a new propagator for a particle in discrete space under the influence of a time-dependent field. With this result we are able to control the shape of caustics emerging from a point-like source, as the explicit form of the wavefronts can be put in terms of the external field.
