Dipolar Bose-Einstein condensates at Finite temperature
Shai Ronen, John Bohn
We study a Bose-Einstein condensate (BEC) of a dilute gas with dipolar interactions, at finite temperature, using the Hartree-Fock-Bogoliubov (HFB) theory within the Popov approxim…
Bogoliubov modes of a dipolar condensate in a cylindrical trap
Shai Ronen, Daniele E. C. Bortolotti, John L. Bohn
The calculation of properties of Bose-Einstein condensates with dipolar interactions has proven a computationally intensive problem due to the long range nature of the interactions…
Dipolar Bose-Einstein condensates with dipole-dependent scattering length
Shai Ronen, Daniele C. E. Bortolotti, D. Blume +1
We consider a Bose-Einstein condensate of polar molecules in a harmonic trap, where the effective dipole may be tuned by an external field. We demonstrate that taking into account…
Stability of fermionic Feshbach molecules in a Bose-Fermi mixture
Alexander V. Avdeenkov, Daniele C. E. Bortolotti, John. L. Bohn
In the wake of successful experiments in Fermi condensates, experimental attention is broadening to study resonant interactions in degenerate Bose-Fermi mixtures. Here we consider…
Bose-Fermi Mixtures Near an Interspecies Feshbach Resonance: Testing a Non Equilibrium Approach
Daniele C. E. Bortolotti, Alexandr V. Avdeenkov, Christopher Ticknor +1
We test a non equilibrium approach to study the behavior of a Bose-Fermi mixture of alkali atoms in the presence of a Feshbach resonance between bosons and fermions. To this end we…
Resonant control of elastic collisions in an optically trapped Fermi gas of atoms
T. Loftus, C. A. Regal, C. Ticknor +2
We have loaded an ultracold gas of fermionic atoms into a far off resonance optical dipole trap and precisely controlled the spin composition of the trapped gas. We have measured a…
