Resonance in a driven two-level system: analytical results without the rotating wave approximation

Yu. V. Bezvershenko, P. I. Holod

We consider the problem of two-level system dynamics induced by the time-dependent field B={a(t)cosωt,a(t)sinωt,ω_0}, with a(t) \sim cn(νt,k). The problem is exactly analytically s…
