Autor: Francesco Vercesi, Quentin Fontaine, Sylvain Ravets, Jacqueline Bloch, Maxime Richard, Léonie Canet, Anna Minguzzi

Publikováno v: Physical Review Research, Vol 5, Iss 4, p 043062 (2023)

We consider a one-dimensional driven-dissipative exciton-polariton condensate under incoherent pump, described by the stochastic generalized Gross-Pitaevskii equation. It was shown that the condensate phase dynamics maps under some assumptions to the

Kardar-Parisi-Zhang universality in discrete two-dimensional driven-dissipative exciton polariton condensates

Autor: Konstantinos Deligiannis, Quentin Fontaine, Davide Squizzato, Maxime Richard, Sylvain Ravets, Jacqueline Bloch, Anna Minguzzi, Léonie Canet

Publikováno v: Physical Review Research, Vol 4, Iss 4, p 043207 (2022)

The statistics of the fluctuations of quantum many-body systems are highly revealing of their nature. In driven-dissipative systems displaying macroscopic quantum coherence, as exciton polariton condensates under incoherent pumping, the phase dynamic

Revealing universal behaviours is a hallmark of statistical physics. Phenomena such as the stochastic growth of crystalline surfaces(1) and of interfaces in bacterial colonies(2), and spin transport in quantum magnets(3-6) all belong to the same univ

Functional renormalisation group for turbulence

Autor: Léonie Canet

Turbulence is a complex nonlinear and multi-scale phenomenon. Although the fundamental underlying Navier-Stokes equations have been known for two centuries, it remains extremely challenging to extract from them the statistical properties of turbulenc

International audience; Stochastic phenomena are often described by Langevin equations, which serve as a mesoscopic model for microscopic dynamics. It is known since the work of Parisi and Sourlas that reversible (or equilibrium) dynamics present sup

Spatio-temporal correlations in three-dimensional homogeneous and isotropic turbulence

Physics of Fluids, American Institute of Physics, 2021, 33 (4), pp.045114. ⟨10.1063/5.0046677⟩

We use direct numerical simulations (DNSs) of the forced Navier–Stokes equation for a three-dimensional incompressible fluid in order to test recent theoretical predictions. We study the two- and three-point spatiotemporal correlation functions of

Exciton-polariton condensates under driven-dissipative conditions are predicted to belong to the Kardar-Parisi-Zhang (KPZ) universality class, the dynamics of the condensate phase satisfying the same equation as for classical stochastic interface gro

Spatio-temporal correlation functions in scalar turbulence from functional renormalization group

Publikováno v: Phys.Fluids
Phys.Fluids, 2021, 33 (6), pp.065109. ⟨10.1063/5.0050515⟩

We provide the leading behavior at large wavenumbers of the two-point correlation function of a scalar field passively advected by a turbulent flow. We first consider the Kraichnan model, in which the turbulent carrier flow is modeled by a stochastic

Eulerian spatiotemporal correlations in passive scalar turbulence

Publikováno v: Physical Review Fluids
Physical Review Fluids, 2021, 6 (12), pp.124606. ⟨10.1103/PhysRevFluids.6.124606⟩

We study the spatio-temporal two-point correlation function of passively advected scalar fields in the inertial-convective range in three dimensions by means of numerical simulations. We show that at small time delays $t$ the correlations decay as a
