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…
Interferences between Bogoliubov excitations and their impact on the evidence of superfluidity in a paraxial fluid of light
Quentin Fontaine, Pierre-Elie Larré, Giovanni Lerario +7
Paraxial fluids of light represent an alternative platform to atomic Bose-Einstein condensates and superfluid liquids for the study of the quantum behaviour of collective excitatio…
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…
Postquench prethermalization in a disordered quantum fluid of light
P. -É. Larré, D. Delande, N. Cherroret
We study the coherence of a disordered and interacting quantum light field after propagation along a nonlinear optical fiber. Disorder is generated by a cross-phase modulation with…
Quantum signature of analog Hawking radiation in momentum space
D. Boiron, A. Fabbri, P. -É. Larré +3
We consider a sonic analog of a black hole realized in the one-dimensional flow of a Bose-Einstein condensate. Our theoretical analysis demonstrates that one- and two-body momentum…
Polarization hydrodynamics in a one-dimensional polariton condensate
P. -É Larré, N. Pavloff, A. M. Kamchatnov
We study the hydrodynamics of a nonresonantly-pumped polariton condensate in a quasi-one-dimensional quantum wire taking into account the spin degree of freedom. We clarify the rel…
Nonlinear waves of polarization in two-component Bose-Einstein condensates
A. M. Kamchatnov, Y. V. Kartashov, P. -É. Larré +1
Waves with different symmetries exist in two-component Bose-Einstein condensates (BECs) whose dynamics is described by a system of coupled Gross-Pitaevskii (GP) equations. A first…
Hawking radiation in a two-component Bose-Einstein condensate
P. -É. Larré, N. Pavloff
We consider a simple realization of an event horizon in the flow of a one-dimensional two-component Bose-Einstein condensate. Such a condensate has two types of quasiparticles; In…
Wave pattern induced by a localized obstacle in the flow of a one-dimensional polariton condensate
P. -É Larré, N. Pavloff, A. M. Kamchatnov
Motivated by recent experiments on generation of wave patterns by a polariton condensate incident on a localized obstacle, we study the characteristics of such flows under the cond…
Quantum fluctuations around black hole horizons in Bose-Einstein condensates
P. -É. Larré, A. Recati, I. Carusotto +1
We study several realistic configurations allowing to realize an acoustic horizon in the flow of a one dimensional Bose-Einstein condensate. In each case we give an analytical desc…
