Effect of Dimple Potential on Ultraslow Light in a Bose-Einstein Condensate

Title variants
Languages of publication
We investigate the propagation of ultraslow optical pulse in atomic Bose-Einstein condensate in a harmonic trap decorated with a dimple potential. The role of dimple potential on the group velocity and time delay is studied. Since we consider the interatomic scattering interactions, nonlinear Schrödinger equation or the Gross-Pitaevskii equation is used in order to get the density profile of the atomic system. We find large group delays of order 1 ms in an atomic Bose-Einstein condensate in a harmonic trap with a deep dimple potential.
