Bose-Einstein condensation in systems with flux equilibrium

Victor S. L'vov, Anna Pomyalov, Sergey V. Nazarenko +4

We consider flux equilibrium in dissipative nonlinear wave systems subject to external energy pumping. In such systems, the elementary excitations, or quasiparticles, can create a…

Interaction quenches in nonzero temperature fermionic condensates

Hadrien Kurkjian, Victor E. Colussi, Paul Dyke +2

We revisit the study of amplitude oscillations in a pair condensate of fermions after an interaction quench, and generalize it to nonzero temperature. For small variations of the o…

Higgs oscillations in a unitary Fermi superfluid

P. Dyke, S. Musolino, H. Kurkjian +7

Symmetry-breaking phase transitions are central to our understanding of states of matter. When a continuous symmetry is spontaneously broken, new excitations appear that are tied t…

Stationary transport above the critical velocity in a one-dimensional superflow past an obstacle

Juliette Huynh, Frédéric Hébert, Pierre-Élie Larré +1

We consider in this work the different possible stationary flows of a one dimensional quantum fluid in the mean-field regime. We focus on the supersonic regime where a transition f…

Critical velocity of a two-dimensional superflow past a potential barrier of arbitrary penetrability

Juliette Huynh, Frédéric Hébert, Mathias Albert +1

We theoretically investigate the critical velocity for dissipationless motion of a two-dimensional superfluid past a static potential barrier of large width. The circular-shaped ba…

High-momentum oscillating tails of strongly interacting 1D gases in a box

Gianni Aupetit-Diallo, Silvia Musolino, Mathias Albert +1

We study the momentum distribution of strongly interacting one-dimensional mixtures of particles at zero temperature in a box potential. We find that the magnitude of the t…
