Quasiequilibrium self-gravitating systems

K Ourabah - Physical Review D, 2020 - APS
Because of the long-range nature of the gravitational interaction, self-gravitating systems
never reach thermal equilibrium in the thermodynamic limit but remain trapped in …

Landau damping and particle trapping in the quantum regime

JT Mendonça - Reviews of Modern Plasma Physics, 2023 - Springer
We review research on electron plasma waves and Landau damping in the quantum
regime. Quantum kinetic equations are also briefly reviewed. Particle trapping, harmonic …

Alternative fidelity measure between quantum states

PEMF Mendonça, RJ Napolitano, MA Marchiolli… - Physical Review A …, 2008 - APS
We propose an alternative fidelity measure (namely, a measure of the degree of similarity)
between quantum states and benchmark it against a number of properties of the standard …

On the collective properties of quantum media

K Ourabah - The European Physical Journal Plus, 2023 - Springer
We discuss the hydrodynamic representation of a wide class of quantum media exhibiting
similar elementary excitations and dispersion properties. The representation covers …

Photon bubbles in ultracold matter

JT Mendonça, R Kaiser - Physical review letters, 2012 - APS
We show that static and oscillating photon bubbles can be excited by diffused light in the
laser cooled matter confined in a magneto-optical trap. The bubble instability is due to the …

Schrödinger–Poisson systems under gradient fields

K Ourabah - Scientific Reports, 2022 - nature.com
A singularity-free generalisation of Newtonian gravity can be constructed (Lazar in Phys Rev
D 102: 096002, 2020) within the framework of gradient field theory. This procedure offers a …

The Lake equation as a supercritical mean-field limit

M Rosenzweig, S Serfaty - arXiv preprint arXiv:2408.14642, 2024 - arxiv.org
We study so-called supercritical mean-field limits of systems of trapped particles moving
according to Newton's second law with either Coulomb/super-Coulomb or regular …

Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity

C Gomes, K Ourabah - The European Physical Journal C, 2023 - Springer
We present a quantum treatment of the Jeans gravitational instability in the Newtonian limit
of the non-minimal matter-curvature coupling gravity model. By relying on Wigner functions …

Cold and hot atomic vapors: a testbed for astrophysics?

Q Baudouin, W Guerin, R Kaiser - Annual Review of Cold Atoms …, 2014 - World Scientific
Atomic physics experiments, based on hot vapors or laser-cooled atomic samples, may be
useful to simulate some astrophysical problems, where radiation pressure, radiative …

Kinetic theory for transverse optomechanical instabilities

E Tesio, GRM Robb, T Ackemann, WJ Firth, GL Oppo - Physical review letters, 2014 - APS
We investigate transverse symmetry-breaking instabilities emerging from the
optomechanical coupling between light and the translational degrees of freedom of a …
