The quantum dynamics of a delta-kicked driven particle in a star-shaped network is studied by obtaining an exact solution for the time-dependent Schrödinger equation within a single kicking period. The timedependence of the average kinetic energy and the Gaussian wave packet evolution are analyzed.
Keywords: quantum graph,periodically kicked system,wave packet dynamics.
