One-dimensional two-component fermions with contact even-wave repulsion and SU(2) breaking near-resonant odd-wave attraction
D. V. Kurlov, S. I. Matveenko, V. Gritsev +1
We consider a one-dimensional (1D) two-component atomic Fermi gas with contact interaction in the even-wave channel (Yang-Gaudin model) and study the effect of an SU(2) symmetry br…
Momentum distribution and coherence of a weakly interacting Bose gas after a quench
Giovanni I. Martone, Pierre-Élie Larré, Alessandro Fabbri +1
We consider a weakly interacting uniform atomic Bose gas with a time-dependent nonlinear coupling constant. By developing a suitable Bogoliubov treatment we investigate the time ev…
Stable p-wave resonant two-dimensional Fermi-Bose dimers
Betzalel Bazak, Dmitry S. Petrov
We consider two-dimensional weakly-bound heterospecies molecules formed in a Fermi-Bose mixture with attractive Fermi-Bose and repulsive Bose-Bose interactions. Bosonic exchanges l…
Dimensional crossover for the beyond-mean-field correction in Bose gases
Tobias Ilg, Jan Kumlin, Luis Santos +2
We present a detailed beyond-mean-field analysis of a weakly interacting Bose gas in the crossover from three to low dimensions. We find an analytical solution for the energy and p…
Reaction kinetics of ultracold molecule-molecule collisions
Daniel K. Hoffmann, Thomas Paintner, Wolfgang Limmer +2
Studying chemical reactions on a state-to-state level tests and improves our fundamental understanding of chemical processes. For such investigations it is convenient to make use o…
Drag force and superfluidity in the supersolid stripe phase of a spin-orbit-coupled Bose-Einstein condensate
Giovanni I. Martone, Georgy V. Shlyapnikov
The phase diagram of a spin-orbit-coupled two-component Bose gas includes a supersolid stripe phase, which is featuring density modulations along the direction of the spin-orbit co…
