Kinetic Integrals in the Kinetic Theory of dissipative gases

open access: yes, 2003
The kinetic theory of gases, including Granular Gases, is based on the Boltzmann equation. Many properties of the gas, from the characteristics of the velocity distribution function to the transport coefficients may be expressed in terms of functions of ...

The Schauder estimate in kinetic theory with application to a toy nonlinear model [PDF]

open access: yes, 2020
This article is concerned with the Schauder estimate for linear kinetic Fokker-Planck equations with H\"older continuous coefficients. This equation has an hypoelliptic structure.

Worldline construction of a covariant chiral kinetic theory [PDF]

open access: yes, 2017
We discuss a novel worldline framework for computations of the chiral magnetic effect (CME) in ultrarelativistic heavy-ion collisions. Starting from the fermion determinant in the QCD effective action, we show explicitly how its real part can be ...

The Breakdown of Kinetic Theory in Granular Shear Flows

open access: yes, 2005
We examine two basic assumptions of kinetic theory-- binary collisions and molecular chaos-- using numerical simulations of sheared granular materials.

Relativistic Chiral Kinetic Theory from Quantum Field Theories [PDF]

open access: yes, 2016
The chiral kinetic theory of Weyl fermions with collisions in the presence of weak electric and magnetic fields is derived from quantum field theories.

Consistent Chiral Kinetic Theory in Weyl Materials: Chiral Magnetic Plasmons. [PDF]

open access: yesPhysical Review Letters, 2016
We argue that the correct definition of the electric current in the chiral kinetic theory for Weyl materials should include the Chern-Simons contribution that makes the theory consistent with the local conservation of the electric charge in ...

Deriving improved plasma fluid equations from collisional kinetic theory

open access: yesFrontiers in Astronomy and Space Sciences
IntroductionDeveloping a quantitative understanding of wave plasma processes in the lower ionosphere requires a reasonably accurate theoretical description of the underlying physical processes.

Spin diffusion and relaxation in three-dimensional isotropic Heisenberg antiferromagnets

open access: yes, 1998
A theory is proposed for kinetic effects in isotropic Heisenberg antiferromagnets at temperatures above the Neel point. A metod based on the analysis of a set of Feynman diagrams for the kinetic coefficients is developed for studying the critical ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Transport Coefficients for Granular Media from Molecular Dynamics Simulations

open access: yes, 1999
Under many conditions, macroscopic grains flow like a fluid; kinetic theory pred icts continuum equations of motion for this granular fluid. In order to test the theory, we perform event driven molecular simulations of a two-dimensional gas of inelastic ...
