Properties of the diffusion and drift kinetic coefficients in momentum space for a cold Fermi system [PDF]
Ядерна фізика та енергетика, 2023 Using the methods of kinetic theory, expressions for the diffusion and drift coefficients for a cold Fermi system are obtained. Their dependencies on the momentum are calculated for the step distribution function as well as in the case of excitation of a

Mpemba-like effect protocol for granular gases of inelastic and rough hard disks
Frontiers in Physics, 2022 We study the conditions under which a Mpemba-like effect emerges in granular gases of inelastic and rough hard disks driven by a class of thermostats characterized by the splitting of the noise intensity into translational and rotational counterparts ...

Chiral kinetic theory from effective field theory revisited
Journal of High Energy Physics, 2019 We revisit the chiral kinetic equation from high density effective theory approach, finding a chiral kinetic equation differs from counterpart derived from field theory in high order terms in the O(1/μ) expansion, but in agreement with the equation ...

International Journal of Modern Physics B, 2000 The short time behavior of a disturbed system is influenced by off-shell motion and characterized by the reduced density matrix possessing high energetic tails. After this short time regime the time evolution is controlled by small gradients. This leads to a nonlocal Boltzmann equation for the quasiparticle distribution and a functional relating the ...

Kinetic Theory beyond the Stosszahlansatz
Entropy, 2017 In a recent paper (Chliamovitch, et al., 2015), we suggested using the principle of maximum entropy to generalize Boltzmann’s Stosszahlansatz to higher-order distribution functions.

Microscopic theory of adsorption kinetics
The Journal of Chemical Physics, 2023 Adsorption is the accumulation of a solute at an interface that is formed between a solution and an additional gas, liquid, or solid phase. The macroscopic theory of adsorption dates back more than a century and is now well-established. Yet, despite recent advancements, a detailed and self-contained theory of single-particle adsorption is still lacking.

Kinetic theory of cluster dynamics [PDF]
Physica D: Nonlinear Phenomena, 2016 In a Newtonian system with localized interactions the whole set of particles is naturally decomposed into dynamical clusters, defined as finite groups of particles having an influence on each other's trajectory during a given interval of time. For an ideal gas with short-range intermolecular force, we provide a description of the cluster size ...

Jet thermalization in QCD kinetic theory
Journal of High Energy Physics, 2023 We perform numerical studies in the framework of QCD kinetic theory to investigate the energy and angular profiles of a high energy parton — as a proxy for a jet produced in heavy ion collisions — passing through a Quark-Gluon Plasma (QGP).

Kac’s program in kinetic theory [PDF]
Inventiones mathematicae, 2012 101 pages. This preprint supersedes hal-00447988 / arXiv:1001.2994. It entirely includes these previous results and contains new results (relaxation rates independent of the number of particles, propagation of entropic chaos, comparison with approaches based on the BBGKY hierarchy) and some additional explanations and historical notes.

Kinetic Theory of Coupled Oscillators [PDF]
Physical Review Letters, 2007 We present an approach for the description of fluctuations that are due to finite system size induced correlations in the Kuramoto model of coupled oscillators. We construct a hierarchy for the moments of the density of oscillators that is analogous to the BBGKY hierarchy in the kinetic theory of plasmas and gases.
