Effective quantum kinetic theory for spin transport of fermions with collsional effects [PDF]
Journal of High Energy Physics, 2020 We systematically derive the collision term for the axial kinetic theory, a quantum kinetic theory delineating the coupled dynamics of the vector/axial charges and spin transport carried by the massive spin-1/2 fermions traversing a medium. We employ the

Kinetic theory of discontinuous shear thickening [PDF]
EPJ Web of Conferences, 2017 A simple kinetic theory to exhibit a discontinuous shear thickening (DST) is proposed. The model includes a collision integral, a drag from environment and an environmental temperature Tex as well as a shear term.

The Einstein-Vlasov System/Kinetic Theory [PDF]
Living Reviews in Relativity, 2005 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 Einsteins equations to a kinetic matter model. Kinetic theory has been an important field of research

Quantum kinetic theory of plasmas [PDF]
Reviews of Modern Plasma Physics, 2021 As is well known, for plasmas of high density and modest temperature, the classical kinetic theory needs to be extended. Such extensions can be based on the Schrödinger Hamiltonian, applying a Wigner transform of the density matrix, in which case the ...

Covariant spin kinetic theory I: collisionless limit [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2020 We develop a covariant kinetic theory for massive fermions in a curved spacetime and an external electromagnetic field based on quantum field theory. We derive four coupled semi-classical kinetic equations accurate to , which describe the transports of ...

Zilch vortical effect, Berry phase, and kinetic theory [PDF]
Journal of High Energy Physics, 2020 Rotating photon gas exhibits a chirality separation along the angular velocity which is manifested through a generation of helicity and zilch currents. In this paper we study this system using the corresponding Wigner function and construct elements of ...

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