Vortex lattices: from the hydrodynamic to the quantum hall regime
L. O. Baksmaty, S. J. Woo, S. Choi +1
We describe the excitations of a vortex lattice in rapidly rotating trapped Bose-Einstein Condensates, focusing on their evolution from the hydrodynamic to the quantum Hall regimes…
An example of quantum control via Feshbach resonance in Bose-Einstein condensates
S. Choi, N. P. Bigelow
We present a simple example of quantum control in Bose-Einstein condensates via Feshbach resonance. By tuning an initially positive scattering length to zero, it is possible to gen…
Excitation spectroscopy of vortex lattices in a rotating Bose-Einstein condensate
S. J. Woo, L. O. Baksmaty, S. Choi +1
Excitation spectroscopy of vortex lattices in rotating Bose-Einstein condensates is described. We numerically obtain the Bogoliubov-deGenne quasiparticle excitations for a broad ra…
Tkachenko waves in rapidly rotating Bose-Einstein condensates
L. O. Baksmaty, S. J. Woo, S. Choi +1
We present a mean-field theory numerical study of Tkachenko waves of a vortex lattice in trapped atomic Bose-Einstein condenstates. Our results show remarkable qualitative and quan…
Excitation spectrum of vortex lattices in rotating Bose-Einstein condensates
S. Choi, L. O. Baksmaty, S. J. Woo +1
Using the coarse grain averaged hydrodynamic approach, we calculate the excitation spectrum of vortex lattices sustained in rotating Bose-Einstein condensates. The spectrum gives t…
Generalized coherent state representation of Bose-Einstein condensates
V. Chernyak, S. Choi, S. Mukamel
We show that the quantum many-body state of Bose-Einstein condensates (BEC) consistent with the time-dependent Hartree-Fock-Bogoliubov (TDHFB) equations is a generalized coherent s…
Squeezing and temperature measurement in Bose-Einstein Condensates
J. Rogel-Salazar, S. Choi, G. H. C. New +1
In this paper we discuss the presence of temperature-dependent squeezing in the collective excitations of trapped Bose-Einstein condensates, based on a recent theory of quasipartic…
Characterisation of the dynamical quantum state of a zero temperature Bose-Einstein condensate
J. Rogel-Salazar, S. Choi, G. H. C. New +1
We describe the quantum state of a Bose-Einstein condensate at zero temperature. By evaluating the Q-function we show that the ground state of Bose-Einstein condensate under the Ha…
