Net current generation in a 1D quantum ring at zero magnetic field

Physica E27, 278 (2005) We study a non-adiabatic excitation of an electron system in a 1D quantum ring radiated by a short THz pulse. The response of two models, a continuous and discrete, is explored. By introducing a spatial asymmetry in the external perturbation a net current can be generated in...
