Quantitative Determination of Temperature in the Approach to Magnetic Order of Ultracold Fermions in an Optical Lattice

Robert Jördens, Leticia Tarruell, Daniel Greif +12

We perform a quantitative simulation of the repulsive Fermi-Hubbard model using an ultracold gas trapped in an optical lattice. The entropy of the system is determined by comparing…

Vortex structures in rotating Bose-Einstein condensates

S. I. Matveenko, D. Kovrizhin, S. Ouvry +1

We present an analytical solution for the vortex lattice in a rapidly rotating trapped Bose-Einstein condensate (BEC) in the lowest Landau level and discuss deviations from the Tho…

Microwave-induced Fano-Feshbach resonances

D. J. Papoular, G. V. Shlyapnikov, J. Dalibard

We investigate the possibility to control the s-wave scattering length for the interaction between cold bosonic atoms by using a microwave field. Our scheme applies to any atomic s…

Finite size effects in global quantum quenches: examples from free bosons in an harmonic trap and the one-dimensional Bose-Hubbard model

Guillaume Roux

We investigate finite size effects in quantum quenches on the basis of simple energetic arguments. Distinguishing between the low-energy part of the excitation spectrum, below a mi…

Bogoliubov Theory of acoustic Hawking radiation in Bose-Einstein Condensates

A. Recati, N. Pavloff, I. Carusotto

We apply the microscopic Bogoliubov theory of dilute Bose-Einstein condensates to analyze quantum and thermal fluctuations in a flowing atomic condensate in the presence of a sonic…

Atom-dimer scattering and long-lived trimers in fermionic mixtures

J. Levinsen, T. G. Tiecke, J. T. M. Walraven +1

We consider a heteronuclear fermionic mixture on the molecular side of an interspecies Feshbach resonance and discuss atom-dimer scattering properties in uniform space and in the p…
