A derivation of the kappa distribution in non-equilibrium, steady-state plasmas

Autor: Davis, Sergio, Avaria, Gonzalo, Bora, Biswajit, Jain, Jalaj, Moreno, José, Pavez, Cristian, Soto, Leopoldo

Kappa-distributed velocities in plasmas are common in a wide variety of settings, from low-density to high-density plasmas, and appear in both space and laboratory plasmas. Despite being widely used as a model, the origin of the kappa distribution re

Computational Statistical Mechanics of a confined, three-dimensional Coulomb gas

Autor: Davis, Sergio, Jain, Jalaj, Bora, Biswajit

Publikováno v: Phys. Rev. E 102, 042137 (2020)

The thermodynamic properties of systems with long-range interactions is still an ongoing challenge, both from the point of view of theory as well as computer simulation. In this work we study a model system, a Coulomb gas confined inside a sphere, by

Report

Single-particle velocity distributions of collisionless, steady-state plasmas must follow Superstatistics

Autor: Davis, Sergio, Avaria, Gonzalo, Bora, Biswajit, Jain, Jalaj, Moreno, José, Pavez, Cristian, Soto, Leopoldo

Publikováno v: Phys. Rev. E 100, 023205 (2019)

The correct modelling of velocity distribution functions for particles in steady-state plasmas is a central element in the study of nuclear fusion and also in the description of space plasmas. In this work, a statistical mechanical formalism for the
