Critical speed of a binary superfluid of light

Pierre-Élie Larré, Claire Michel, Nicolas Cherroret

We theoretically study the critical speed for superfluid flow of a two-dimensional miscible binary superfluid of light past a polarization-sensitive optical obstacle. This speed co…

Diffraction induced quantum chaos in a one-dimensional Bose gas

M. Olshanii, G. Aupetit-Diallo, S. G. Jackson +2

We investigate the Lieb--Liniger model of interacting one-dimensional bosons coupled to a localized impurity, modeled by a delta barrier. While the Lieb--Liniger gas is integrable,…

Engineering Anderson Localization in Arbitrary Dimensions with Interacting Quasiperiodic Kicked Bosons

H. Olsen, P. Vignolo, M. Albert

We study the interplay of interactions and quasiperiodic driving in the Lieb-Liniger model of one-dimensional bosons subjected to a sequence of delta kicks. Building on the known m…

Probing non-ergodicity and symmetry via coherent forward scattering in a shaken rotor

F. Arrouas, J. Hébraud, N. Ombredane +9

The Coherent Backscattering (CBS) peak is a well-known interferential signature of weak localization in disordered or chaotic systems. More recently, a second interference feature…

Strong and weak wave turbulence regimes in Bose-Einstein condensates

Ying Zhu, Giorgio Krstulovic, Sergey Nazarenko

When a turbulent Bose-Einstein condensate is driven out-of-equilibrium at a scale much smaller than the system size, nonlinear wave interactions transfer particles towards large sc…

Necklace Ansatz for strongly repulsive spin mixtures on a ring

Gianni Aupetit-Diallo, Giovanni Pecci, Artem Volosniev +3

We propose an alternative to the Bethe Ansatz method for strongly-interacting fermionic (or bosonic) mixtures on a ring. Starting from the knowledge of the solution for single-comp…

Observation of Relaxation Stages in a Nonequilibrium Closed Quantum System: Decaying Turbulence in a Trapped Superfluid

M. A. Moreno-Armijos, A. R. Fritsch, A. D. García-Orozco +7

The dynamics of non-equilibrium closed quantum systems and their route to thermalization are of fundamental interest to several fields, from cosmology to particle physics. However,…

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…

Persistent currents in a strongly interacting multicomponent Bose gas on a ring

Giovanni Pecci, Gianni Aupetit-Diallo, Mathias Albert +2

We consider a two-component Bose-Bose mixture at strong repulsive interactions in a tightly confining, one-dimensional ring trap and subjected to an artificial gauge field. By empl…

Direct and inverse cascades in turbulent Bose-Einstein condensate

Ying Zhu, Boris Semisalov, Giorgio Krstulovic +1

When a Bose-Einstein condensate (BEC) is driven out of equilibrium, density waves interact non-linearly and trigger turbulent cascades. In a turbulent BEC, energy is transferred to…

Superfluidity vs prethermalisation in a nonlinear Floquet system

Sen Mu, Nicolas Macé, Jiangbin Gong +3

We show that superfluidity can be used to prevent thermalisation in a nonlinear Floquet system. Generically, periodic driving boils an interacting system to a featureless infinite…

Low-energy prethermal phase and crossover to thermalization in nonlinear kicked rotors

Maxime Martinez, Pierre-Élie Larré, Dominique Delande +1

In the presence of interactions, periodically-driven quantum systems generically thermalize to an infinite-temperature state. Recently, however, it was shown that in random kicked…
