Abstract:
We study the dynamics of a Gaussian wave packet in a branched system of periodic lattices driven by an external time-dependent field. Motivated by recent numerical experiments with the manipulation of wave packet transmission in quantum star graph, we provide further discussion based on some achievements obtained from one-dimensional tight-binding models with arbitrary external time-dependent fields and on numerical calculations.
Keywords:
quantum graph, periodically-driven system, directed transport, wave packet dynamics.
