Stability and Excitations of a Dipolar Bose-Einstein Condensate with a Vortex
Ryan M. Wilson, Shai Ronen, John L. Bohn
We study the stability of singly- and doubly-quantized vortex states of harmonically trapped dipolar Bose-Einstein Condensates (BECs) by calculating the low-lying excitations of th…
Generalized Mean Field Approach to a Resonant Bose-Fermi Mixture
D. C. E. Bortolotti, A. V. Avdeenkov, J. L. Bohn
We formulate a generalized mean-field theory of a mixture of fermionic and bosonic atoms, in which the fermion-boson interaction can be controlled by a Feshbach resonance. The theo…
Dynamical pattern formation during growth of a dual-species Bose-Einstein condensate
Shai Ronen, John L. Bohn, Laura E. Halmo +1
We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs durin…
Manifestations of the Roton Mode in Dipolar Bose-Einstein Condensates
Ryan M. Wilson, Shai Ronen, Han Pu +1
We investigate the structure of trapped Bose-Einstein condensates (BECs) with long-range anisotropic dipolar interactions. We find that a small perturbation in the trapping potenti…
p-wave Feshbach molecules
J. P. Gaebler, J. T. Stewart, J. L. Bohn +1
We have produced and detected molecules using a p-wave Feshbach resonance between 40K atoms. We have measured the binding energy and lifetime for these molecules and we find that t…
