Beyond Maxwell-Boltzmann: Transport in Quasiequilibrium Plasmas
Kamel Ourabah
Space plasmas are generally characterized by non-Maxwellian distributions with suprathermal populations, as routinely revealed by in situ observations. Such departures from standar…
Jeans analysis in modified gravity: A general formulation
Ryan Khaled, Kamel Ourabah
We study the Jeans instability of a self-gravitating fluid in the context of alternative gravitational theories. Our formulation accommodates arbitrary corrections to the Newtonian…
Reaction Rates in Quasiequilibrium States
Kamel Ourabah
Non-Maxwellian distributions are commonly observed across a wide range of systems and scales. While direct observations provide the strongest evidence for these distributions, they…
Jeans analysis in fractional gravity
Kamel Ourabah
It has recently been demonstrated [A. Giusti, Phys. Rev. D 101, 124029 (2020)] that characteristic traits of Milgrom's modified Newtonian dynamics (MOND) can be replicated from an…
The Other Way Around: From Alternative Gravity to Entropy
Kamel Ourabah
Since the seminal work of Verlinde, the idea that gravity may be an emergent force of entropic origin has gained widespread attention. Many generalizations of this key idea have be…
A self-gravitating system composed of baryonic and dark matter analysed from the post-Newtonian Boltzmann equations
Gilberto M. Kremer, Kamel Ourabah
We study the Jeans gravitational instability for a mixture of baryonic and dark matter particles, in the post-Newtonian approximation. We adopt a kinetic model consisting of a coup…
On the collective properties of quantum media
Kamel Ourabah
We discuss the hydrodynamic representation of a wide class of quantum media exhibiting similar elementary excitations and dispersion properties. The representation covers quantum s…
Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity
Cláudio Gomes, Kamel Ourabah
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 functi…
Gravitational instability with a dark matter background: Exploring the different scenarios
Kamel Ourabah
We study the Jeans-type gravitational instability for a self-gravitating medium composed of two species, baryonic (bright) and dark matter particles, using a hybrid quantum-classic…
