Decoherence and turbulence sources in a long laser

Amy Roche, Svetlana Slepneva, Anton Kovalev +5

We investigate the turn-on process in a laser cavity where the roundtrip time is several orders of magnitude greater than the active medium timescales. In this long delay limit the…

Nonequilibrium steady state in a large magneto-optical trap

Marius Gaudesius, Yong-Chang Zhang, Thomas Pohl +2

Considering light-mediated long-range interactions between cold atoms in a magneto-optical trap (MOT), we present numerical evidence of a nonequilibrium steady state (NESS) for suf…

Explainability as statistical inference

Hugo Henri Joseph Senetaire, Damien Garreau, Jes Frellsen +1

A wide variety of model explanation approaches have been proposed in recent years, all guided by very different rationales and heuristics. In this paper, we take a new route and ca…

Rheology of dense suspensions under shear rotation

Frédéric Blanc, François Peters, Jurriaan J. J. Gillissen +4

Dense non-Brownian suspensions exhibit a spectacular and abrupt drop in viscosity under change of shear direction, as revealed by shear inversions (reversals) or orthogonal superpo…

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…

Discontinuous Shear Thickening (DST) transition with spherical iron particles coated by adsorbed brush polymer

Georges Bossis, Yan Grasselli, Olga Volkova

In this work we explore the rheology of very concentrated (0.55<<0.67) suspensions of carbonyl iron (CI) particles coated by a small polymer. A strong DST is observed in a large…

Static and dynamic properties of self-bound droplets of light in hot vapours

Heitor da Silva, Robin Kaiser, Tommaso Macrì

The propagation of light in nonlinear media is well described by a D nonlinear Schrödinger equation (NLSE) within the paraxial approximation, which is equivalent to the Gross-Pi…

Time delay in 1D disordered media with high transmission

Luis A. Razo-López, J. A. Méndez-Bermúdez, Victor A. Gopar

We study the time delay of reflected and transmitted waves in 1D disordered media with high transmission. Highly transparent and translucent random media are found in nature or can…

Computing non-equilibrium trajectories by a deep learning approach

Eric Simonnet

Predicting the occurence of rare and extreme events in complex systems is a well-known problem in non-equilibrium physics. These events can have huge impacts on human societies. Ne…

Waiting time distributions in Quantum spin hall based heterostructures

F. Schulz, D. Chevallier, M. Albert

For the distinction of the Andreev bound states and Majorana bound states, we study the waiting time distributions (WTDs) for heterostructures, based on one dimensional edge states…

Field and intensity correlations: the Siegert relation from stars to quantum emitters

Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +9

The Siegert relation relates field and intensity temporal correlations. After a historical review of the Siegert relation and the Hanbury Brown and Twiss effect, we discuss the val…

Optical interpretation of linear-optics superradiance and subradiance

S. Asselie, A. Cipris, W. Guerin

Super- and subradiance are usually described in the framework of Dicke collective states, which is an ``atomic picture'' in which the electromagnetic field only provides an effecti…

Operational entanglement-based quantum key distribution over 50 km of real-field optical fibres

Yoann Pelet, Grégory Sauder, Mathis Cohen +4

We present a real field quantum key distribution link based on energy-time entanglement. Three nodes are connected over the city of Nice by means of optical fibers with a total dis…

Hamiltonian derivation of the point vortex model from the two-dimensional nonlinear Schrödinger equation

Jonathan Skipp, Jason Laurie, Sergey Nazarenko

We present a rigorous derivation of the point vortex model starting from the two-dimensional nonlinear Schr{ö}dinger equation, from the Hamiltonian perspective, in the limit of wel…

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…

Experimental study of closed and open microwave waveguide graphs with preserved and partially violated time-reversal invariance

Weihua Zhang, Xiaodong Zhang, Jiongning Che +3

We report on experiments that were performed with microwave waveguide systems and demonstrate that in the frequency range of a single transversal mode they may serve as a model for…

Experimental Observation of Multifractality in Fibonacci Chains

Mattis Reisner, Yanel Tahmi, Frédéric Piéchon +2

The tight-binding model for a chain, where the hopping constants follow a Fibonacci sequence, predicts multifractality in the spectrum and wavefunctions. Experimentally, we realize…

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…
