Query: Effect of Dimple Potential on Ultraslow Light in a Bose-Einstein
  Condensate   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 Schrodinger
equation or Gross-Pitaevskii equation is used in order to get the density
profile of the atomic system. We find large group delays of order 1 msec in an
atomic Bose-Einstein condensate in a harmonic trap with a deep dimple
potential.
