Quantum Kinetic Theory of BEC Lattice Gas:Boltzmann Equations from 2PI-CTP Effective Action
Ana Maria Rey, B. L. Hu, Esteban Calzetta +1
We continue our earlier work [Ana Maria Rey, B. L. Hu, Esteban Calzetta, Albert Roura and Charles W. Clark, Phys. Rev. A 69, 033610 (2004)] on the nonequilibrium dynamics of a Bose…
Effective one-component description of two-component Bose-Einstein condensate dynamics
Zachary Dutton, Charles W. Clark
We investigate dynamics in two-component Bose-Einstein condensates in the context of coupled Gross-Pitaevskii equations and derive results for the evolution of the total density fl…
Mean-field treatment of the damping of the oscillations of a 1D Bose gas in an optical lattice
Julio Gea-Banacloche, Ana Maria Rey, Guido Pupillo +2
We present a theoretical treatment of the surprisingly large damping observed recently in one-dimensional Bose-Einstein atomic condensates in optical lattices. We show that time-de…
Ultracold Fermion Cooling Cycle using Heteronuclear Feshbach Resonances
M. A. Morales, N. Nygaard, J. E. Williams +1
We consider an ideal gas of Bose and Fermi atoms in a harmonic trap, with a Feshbach resonance in the interspecies atomic scattering that can lead to formation of fermionic molecul…
Vortices in attractive Bose-Einstein condensates in two dimensions
L. D. Carr, Charles W. Clark
The form and stability of quantum vortices in Bose-Einstein condensates with attractive atomic interactions is elucidated. They appear as ring bright solitons, and are a generaliza…
Advantages of high-speed technique for quantum key distribution; reply to quant-ph/0407050
J. C. Bienfang, Charles W. Clark, Carl J. Williams +2
We respond to a comment on our high-speed technique for the implementation of free-space quantum key distribution (QKD). The model used in the comment assigns inappropriately high…
