Kinetic theory of long-range interacting systems with angle–action variables and collective effects

PH Chavanis - Physica A: Statistical Mechanics and its Applications, 2012 - Elsevier
We develop a kinetic theory of systems with long-range interactions taking collective effects
and spatial inhomogeneity into account. Starting from the Klimontovich equation and using a …

M ** in Sobolev spaces for the Vlasov-HMF model
E Faou, F Rousset - Archive for Rational Mechanics and Analysis, 2016 - Springer
We consider the Vlasov-HMF (Hamiltonian Mean-Field) model. We consider solutions
starting in a small Sobolev neighborhood of a spatially homogeneous state satisfying a …

The Brownian mean field model

PH Chavanis - The European Physical Journal B, 2014 - Springer
We discuss the dynamics and thermodynamics of the Brownian mean field (BMF) model
which is a system of N Brownian particles moving on a circle and interacting via a cosine …

Kinetic theory of spatially homogeneous systems with long-range interactions: II. Historic and basic equations

PH Chavanis - The European Physical Journal Plus, 2013 - Springer
We provide a short historic of the early development of kinetic theory in plasma physics and
synthesize the basic kinetic equations describing the evolution of systems with long-range …

On linear dam** around inhomogeneous stationary states of the Vlasov-HMF model

E Faou, R Horsin, F Rousset - Journal of Dynamics and Differential …, 2021 - Springer
We study the dynamics of perturbations around an inhomogeneous stationary state of the
Vlasov-HMF (Hamiltonian Mean-Field) model, satisfying a linearized stability criterion …

Modeling and forecasting age-specific drug overdose mortality in the United States

L Böttcher, T Chou, MR D'Orsogna - The European Physical Journal …, 2023 - Springer
Drug overdose deaths continue to increase in the United States for all major drug
categories. Over the past two decades the total number of overdose fatalities has increased …

Kinetic blockings in long-range interacting inhomogeneous systems

JB Fouvry, M Roule - Physical Review E, 2023 - APS
Long-range interacting systems unavoidably relax through Poisson shot noise fluctuations
generated by their finite number of particles, N. When driven by two-body correlations, ie …

Temperature inversion in long-range interacting systems

TN Teles, S Gupta, P Di Cintio, L Casetti - Physical Review E, 2015 - APS
Temperature inversions occur in nature, eg, in the solar corona and in interstellar molecular
clouds: Somewhat counterintuitively, denser parts of the system are colder than dilute ones …
