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

Matching the Nonequilibrium Initial Stage of Heavy Ion Collisions to Hydrodynamics with QCD Kinetic Theory. [PDF]
Physical Review Letters, 2018 High-energy nuclear collisions produce a nonequilibrium plasma of quarks and gluons which thermalizes and exhibits hydrodynamic flow. There are currently no practical frameworks to connect the early particle production in classical field simulations to ...

Kinetic Theory of Spin Diffusion and Superdiffusion in XXZ Spin Chains. [PDF]
Physical Review Letters, 2018 We address the nature of spin transport in the integrable XXZ spin chain, focusing on the isotropic Heisenberg limit. We calculate the diffusion constant using a kinetic picture based on generalized hydrodynamics combined with Gaussian fluctuations: we ...

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 ...

Multiscale models of Covid-19 with mutations and variants
Networks and Heterogeneous Media, 2022 This paper focuses on the multiscale modeling of the COVID-19 pandemic and presents further developments of the model [7] with the aim of showing how relaxations of the confinement rules can generate sequential waves.

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.

Chiral kinetic theory in curved spacetime [PDF]
Physical Review D, 2018 Many-body systems with chiral fermions exhibit anomalous transport phenomena originated from quantum anomalies. Based on quantum field theory, we derive the kinetic theory for chiral fermions interacting with an external electromagnetic field and a ...

Particles on Demand for Kinetic Theory. [PDF]
Physical Review Letters, 2018 A novel formulation of fluid dynamics as a kinetic theory with tailored, on-demand constructed particles removes restrictions on flow speed and temperature as compared to its predecessors, the lattice Boltzmann methods and their modifications. In the new

Kinetic theory of nonthermal fixed points in a Bose gas [PDF]
Physical Review A, 2018 We outline a kinetic theory of non-thermal fixed points for the example of a dilute Bose gas, partially reviewing results obtained earlier, thereby extending, complementing, generalizing and straightening them out.

Analytic structure of nonhydrodynamic modes in kinetic theory [PDF]
The European Physical Journal C, 2017 How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales thus sharing essential features ...
