All Abstracts | Poster Abstracts | Talk Abstracts On generating macroscopic superpositions via nonlinear dynamics of stopped light in a two-component Bose-Einstein condensateCollin Trail, University of Calgary (Session 9c : Friday from 5:30pm - 6:00pm) We investigate a method for generating nonlinear phase shifts on superpositions of photon number states. The light is stored in a Bose-Einstein condensate via electromagnetically-induced transparency memory techniques. The atomic collisions are exploited to generate a nonlinear evolution for the stored state. The stored light is then revived with the nonlinear phase shift imprinted upon it. For the special case of a coherent state input we find that this method can be used to generate an optical cat state. We investigate the validity of using the Thomas-Fermi and mean-field approximations. |
