Maximum population transfer in a periodically driven quantum system

Mostrar todas las versiones(2)

We study the dynamics of a two-level quantum system under the influence of sinusoidal driving in the intermediate-frequency regime. Analyzing the Floquet quasienergy spectrum, we find combinations of the field parameters for which population transfer is optimal and takes place through a series of we...
