Different scattering regimes in twodimensional BoseEinstein condensates
(Springer, 2003)Motivated by the recent efforts to produce lowdimensional condensates, we study the groundstate density profiles of twodimensional BoseEinstein condensed atoms at zero temperature within a meanfield theory. The interplay ... 
Photonic band gap via quantum coherence in vortex lattices of BoseEinstein condensates
(The American Physical Society, 2005)We investigate the optical response of an atomic BoseEinstein condensate with a vortex lattice. We find that it is possible for the vortex lattice to act as a photonic crystal and create photonic band gaps, by enhancing ... 
Quantum correlations among superradiant boseeinstein condensate atoms
(M A I K Nauka  Interperiodica, 2010)Quantum correlations among atoms in superradiant BoseEinstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to ... 
Quantum Dynamics of LongRange Interacting Systems Using the PositiveP and GaugeP Representations
(American Physical Society, 2017)We provide the necessary framework for carrying out stochastic positiveP and gaugeP simulations of bosonic systems with longrange interactions. In these approaches, the quantum evolution is sampled by trajectories in ... 
Quantum entanglement via superradiance of a BoseEinstein condensate
(Institute of Physics PublishingInstitute of Physics Publishing, 2010)We adopt the coherence and builtin swap mechanism in sequential superradiance as a tool for obtaining continuousvariable (electric/magnetic fields) quantum entanglement of two counterpropagating pulses emitted from the ... 
Refractive indexenhanced vortex lattices
(SPIE, 2005)Light propagation through vortex matter in atomic BoseEinstein condensates is examined. It is shown that vortex matter can be used as a photonic crystal by a refractive index enhancement scheme. Band structure of the ... 
Rotons and Bose condensation in Rydbergdressed Bose gases
(American Physical Society, 2020)We investigate the groundstate properties and excitations of Rydbergdressed bosons in both three and two dimensions, using the hypernettedchain EulerLagrange approximation, which accounts for correlations and thus goes ... 
Strongly interacting onedimensional BoseEinstein condensates in harmonic traps
(American Physical Society, 2000)The properties of strongly interacting one dimensional boson condensates in harmonic trap potentials were studied. An equation describing the condensate wave function in the limit of very strong interactions between the ... 
Temperaturedependent density profiles of dipolar droplets
(American Physical Society, 2019)Recently, trapped dipolar gases were observed to form highdensity droplets in a regime where meanfield theory predicts collapse. These droplets present a form of equilibrium where quantum fluctuations are critical for ... 
Vortex lattices in dipolar twocompenent BoseEinstein condensates
(American Physical Society, 20140221)We consider a rapidly rotating twocomponent BoseEinstein condensate with shortrange swave interactions as well as dipolar coupling. We calculate the phase diagram of vortex lattice structures as a function of the ...
