Quantum Kinetic Theory of the Chiral Anomaly [PDF]

, 2017
We present a general quantum kinetic theory of low-field magnetotransport in weakly disordered crystals that accounts fully for the interplay between electric-field-induced interband coherence, Bloch-state scattering, and an external magnetic field.

Turbulence through the Spyglass of Bilocal Kinetics

Entropy, 2018
In two recent papers we introduced a generalization of Boltzmann’s assumption of molecular chaos based on a criterion of maximum entropy, which allowed setting up a bilocal version of Boltzmann’s kinetic equation.

Chiral Kinetic Theory

, 2012
We derive the non-equilibrium kinetic equation describing the motion of chiral massless particles in the regime where it can be considered classically.

Spin kinetic theory - quantum kinetic theory in extended phase space

, 2010
The concept of phase space distribution functions and their evolution is used in the case of en enlarged phase space. In particular, we include the intrinsic spin of particles and present a quantum kinetic evolution equation for a scalar quasi ...

The Einstein-Vlasov sytem/Kinetic theory [PDF]

, 2002
The main purpose of this article is to guide the reader to theorems on global properties of solutions to the Einstein-Vlasov system. This system couples Einstein's equations to a kinetic matter model.

Hydrodynamization in kinetic theory: Transient modes and the gradient expansion [PDF]

Physical Review D, 2016
We explore the transition to hydrodynamics in a weakly-coupled model of quark-gluon plasma given by kinetic theory in the relaxation time approximation with conformal symmetry.

Gravitational Contribution to the Heat Flux in a Simple Dilute Fluid: An Approach Based on General Relativistic Kinetic Theory to First Order in the Gradients

Entropy, 2017
Richard C. Tolman analyzed the relation between a temperature gradient and a gravitational field in an equilibrium situation. In 2012, Tolman’s law was generalized to a non-equilibrium situation for a simple dilute relativistic fluid.

Physical Properties of Helium and Application in Respiratory Care

Encyclopedia, 2023
Helium is a low-density, inert, monoatomic gas that is widely used in medical applications. In respiratory care, Helium is mainly used as an adjunct therapy for patients with severe upper airway obstruction and asthma.

Kinetic-theory description of isoscalar dipole modes [PDF]

, 2001
A semiclassical model, based on a solution of the Vlasov equation for finite systems with moving-surface, is employed to study the isoscalar dipole modes in nuclei. It is shown that, by taking into account the surface degree of freedom, it is possible to

Generalized phase-space kinetic and diffusion equations for classical and dispersive transport

New Journal of Physics, 2014
We formulate and solve a physically-based, phase space kinetic equation for transport in the presence of trapping. Trapping is incorporated through a waiting time distribution function.
