Enhancing capacity of coherent optical information storage and transfer in a Bose-Einstein condensate

摘要: Coherent optical information storage capacity of an atomic Bose-Einstein condensate is examined. Theory slow light propagation in clouds generalized to short pulse regime by taking into account group velocity dispersion. It shown that the number stored pulses can be optimized for a particular coupling laser power, temperature and interatomic interaction strength. Analytical results are derived semi-ideal model using effective uniform density zone approximation. Detailed numerical simulations also performed. found axial profile protects against Furthermore, finite radial size condensate, multi-mode investigated. The modes supported found. Single mode condition determined as function experimentally accessible parameters including trap size, temperature, scattering length. Quantum coherent atom-light schemes proposed enhancing effects.
