Structural interactions in ionic liquids linked to higher order Poisson-Boltzmann equations [PDF]
Physical Review E, 2017 We present a derivation of generalized Poisson-Boltzmann equations starting {from} classical theories of binary fluid mixtures, employing an approach based on the Legendre transform as recently applied to the case of local descriptions of the fluid free ...

Flavored Quantum Boltzmann Equations [PDF]
, 2010 We derive from first principles, using non-equilibrium field theory, the quantum Boltzmann equations that describe the dynamics of flavor oscillations, collisions, and a time-dependent mass matrix in the early universe.

Full Boltzmann equations for leptogenesis including scattering [PDF]
, 2009 We study the evolution of a cosmological baryon asymmetry produced via leptogenesis by means of the full classical Boltzmann equations, without the assumption of kinetic equilibrium and including all quantum statistical factors.

Quantum Boltzmann Equations and Leptogenesis [PDF]
, 2007 The closed time-path formalism is a powerful Green's function formulation to describe non-equilibrium phenomena in field theory and it leads to a complete non-equilibrium quantum kinetic theory.

Comparison of Boltzmann Equations with Quantum Dynamics for Scalar Fields [PDF]
, 2005 Boltzmann equations are often used to study the thermal evolution of particle reaction networks. Prominent examples are the computation of the baryon asymmetry of the universe and the evolution of the quark-gluon plasma after relativistic heavy ion ...

From Kadanoff-Baym to Boltzmann equations for massive spin- 1/2 fermions [PDF]
Physical Review D, 2021 We derive Boltzmann equations for massive spin-1/2 fermions with local and nonlocal collision terms from the Kadanoff--Baym equation in the Schwinger--Keldysh formalism, properly accounting for the spin degrees of freedom.

The Nonclassical Boltzmann Equation and DIffusion-Based Approximations to the Boltzmann Equation [PDF]
SIAM Journal on Applied Mathematics, 2015 We show that several diffusion-based approximations (classical diffusion or SP1, SP2, SP3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be represented exactly by a non-classical transport equation. As a consequence, we indicate a method to solve diffusion-based approximations to the Boltzmann equation via Monte Carlo, with

Global Mild Solutions of the Landau and Non‐Cutoff Boltzmann Equations [PDF]
Communications on Pure and Applied Mathematics, 2019 This paper proves the existence of small‐amplitude global‐in‐time unique mild solutions to both the Landau equation including the Coulomb potential and the Boltzmann equation without angular cutoff.

Flavour mixing transport theory and resonant leptogenesis
Journal of High Energy Physics, 2021 We derive non-equilibrium quantum transport equations for flavour-mixing fermions. We develop the formalism mostly in the context of resonant leptogenesis with two mixing Majorana fermions and one lepton flavour, but our master equations are valid more ...
