The Einstein-Vlasov System/Kinetic Theory

open access: yesLiving Reviews in Relativity, 2011
The main purpose of this article is to provide a guide to theorems on global properties of solutions to the Einstein-Vlasov system. This system couples Einstein’s equations to a kinetic matter model. Kinetic theory has been an important field of research

On the Potential Self-Amplification of Aneurysms Due to Tissue Degradation and Blood Flow Revealed From FSI Simulations

open access: yesFrontiers in Physiology, 2021
Tissue degradation plays a crucial role in the formation and rupture of aneurysms. Using numerical computer simulations, we study the combined effects of blood flow and tissue degradation on intra-aneurysm hemodynamics. Our computational analysis reveals

Solved and unsolved riddles about low-latitude daytime valley region plasma waves and 150-km echoes

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The Earth’s atmosphere near both the geographic and magnetic equators and at altitudes between 120 and 200 km is called the low-latitude valley region (LLVR) and is among the least understood regions of the ionosphere/thermosphere due to its complex ...

Casimir effect in kinetic theory

open access: yesNew Journal of Physics, 2022
We study Casimir effect in equilibrium and non-equilibrium photon gas in the frame of quantum kinetic theory for U (1) gauge field. We derive first the transport, constraint and gauge fixing equations for the photon number distribution from Maxwell’s ...

Heat transport in an optical lattice via Markovian feedback control

open access: yesNew Journal of Physics, 2022
Ultracold atoms offer a unique opportunity to study many-body physics in a clean and well-controlled environment. However, the isolated nature of quantum gases makes it difficult to study transport properties of the system, which are among the key ...

Creep and long-term fracture of a narrow rectangular membrane inside a high rigid matrix with proportional dependence on the transverse pressure on time

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
In this work, we studied the creep and long-term fracture of a narrow rectangular membrane in confined conditions (inside a high rigid matrix) with a proportional dependence on the magnitude of transverse pressure on time.

Mpemba-like effect protocol for granular gases of inelastic and rough hard disks

open access: yesFrontiers 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 ...

Properties of the diffusion and drift kinetic coefficients in momentum space for a cold Fermi system [PDF]

open access: yesЯдерна 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

Chiral kinetic theory from effective field theory revisited

open access: yesJournal 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 ...
