AC Stark effect or time-dependent Aharonov-Bohm effect for particle on a ring
ORAL
Abstract
We study the effect of a time-varying solenoidal vector potential for a quantum particle confined to a ring. The set-up appears to be a time-varying version of the Aharonov-Bohm effect, but since the particle moves in the presence of fields, it is not strictly an Aharonov-Bohm effect. The results are similar to the ac Stark effect, but with a time-varying electric field coming from the vector potential, rather than the scalar potential. We compare and contrast the present effect with the standard ac Stark effect. The signature of this set-up is the generation of quasi-energy side-bands which are observable via spectroscopy.
