Abstract
Our recent work has demonstrated the superradiant writing and reading of collective coherence in a BoseEinstein condensate Phys. Rev. Lett. 99, 220407 2007 . This time we report the drastic improvement of the storage time realized by loading the atoms into an optical dipole trap, wherein an unfavorable spin-dependent phase shift and spatial diffusion of atoms can be suppressed. The measured storage time was 0.57 2 ms, which is limited by the temporal variation of atomic momentum due to harmonic oscillations in the trap.
