Group Seminar LMU: Multi-component slow light in atomic media

During the last several years there has been a great deal of interest in slow light in atomic media. Yet the existing studies restrict to the slow light described in terms of a single component field. In the present talk we shall first review the usual slow and stationary light. Subsequently we shall analyse a double tripod setup involving two pairs of counter-propagating control laser beams. This enables one to create the two-component slow or stationary light exhibiting a number of distinct properties, such as the neutrino type oscillations between its components. If the control lasers carry Orbital Angular Momenta (OAM), there might be the OAM transfer between the components of slow light. In the final part of the talk there will be an overview of the light-induced gauge potential in gases of cold atoms with multiple internal states.
