dc.description.abstract | We investigate the optical response of coherent media, a Bose-Einstein
condensate (BEC), to intense laser pump stimulations and weak probe pulse
propagation.
First, we adopt the coherence in sequential superradiance (SR) as a tool
for continuous-variable (CV) quantum entanglement of two counter-propagating
pulses from the two end-fire modes. In the first-sequence the end-fire and side
mode are CV entangled. In the second sequence of SR, this entanglement is
swapped in between the two opposite end-fire modes.
Second, we investigate the photonic bands of an atomic BEC with a triangular
vortex lattice. Index contrast between the vortex cores and the bulk of
the condensate is achieved through the enhancement of the index via atomic
coherence. Frequency dependent dielectric function is used in the calculations of the bands. We adopt a Poynting vector method to distinguish the photonic band gaps from absorption/gain regimes. | en_US |
