Comment on: Discontinuous codimension-two bifurcation in a Vlasov equation (arXiv:2212.01250)
Tarcísio N. Teles, Renato Pakter, Yan Levin
We comment on the recent work by Yamaguchi and Barré [Phys. Rev. E 107, 054203 (2023)], which uses linear stability analysis of the Vlasov equation to characterize phase transition…
Mixing and Ergodicity in Systems with Long-Range Interactions
Tarcísio Nunes Teles, Renato Pakter, Yan Levin
We present a theory of collisionless relaxation in systems with long-range interactions. Contrary to Lynden-Bell's theory of violent relaxation, which assumes global ergodicity and…
Ensemble inequivalence and absence of quasi-stationary states in long-range random networks
Levon Chakhmakhchyan, Tarcisio N. Teles, Stefano Ruffo
Ensemble inequivalence has been previously displayed only for long-range interacting systems with non-extensive energy. In order to perform the thermodynamic limit, such systems re…
Temperature inversion in long-range interacting systems
Tarcisio N. Teles, Shamik Gupta, Pierfrancesco Di Cintio +1
Temperature inversions occur in nature, e.g., in the solar corona and in interstellar molecular clouds: somewhat counterintuitively, denser parts of the system are colder than dilu…
Ensemble inequivalence in a mean-field XY model with ferromagnetic and nematic couplings
Arkady Pikovsky, Shamik Gupta, Tarcisio N. Teles +4
We explore ensemble inequivalence in long-range interacting systems by studying an XY model of classical spins with ferromagnetic and nematic coupling. We demonstrate the inequival…
Ensemble Inequivalence in Systems with Wave-Particle Interaction
Tarcísio N. Teles, Duccio Fanelli, Stefano Ruffo
The classical wave-particle Hamiltonian is considered in its generalized version, where two modes are assumed to interact with the co-evolving charged particles. The equilibrium st…
Nonequilibrium Statistical Mechanics of Systems with Long-Range Interactions: Ubiquity of Core-Halo Distributions
Yan Levin, Renato Pakter, Felipe B. Rizzato +2
Systems with long-range (LR) forces, for which the interaction potential decays with the interparticle distance with an exponent smaller than the dimensionality of the embedding sp…
Nonequilibrium phase transitions in systems with long-range interactions
Tarcísio N. Teles, Fernanda Benetti, Renato Pakter +1
We introduce a generalized Hamiltonian Mean Field Model (gHMF)-XY model with both linear and quadratic coupling between spins and explicit Hamiltonian dynamics. In addition to the…
Ergodicity Breaking and Parametric Resonances in Systems with Long-Range Interactions
Fernanda P. da C. Benetti, Tarcísio N. Teles, Renato Pakter +1
We explore the mechanism responsible for the ergodicity breaking in systems with long-range forces. In thermodynamic limit such systems do not evolve to the Boltzmann-Gibbs equilib…
Statistical Mechanics of 1d Self-Gravitating Systems: The Core-Halo Distribution
Tarcísio Nunes Teles, Yan Levin, Renato Pakter
We study, using both theory and simulations, a system of self-gravitating sheets. A new statistical mechanics theory - free of any adjustable parameters - is derived to quantitativ…
Statistical Mechanics of Unbound Two Dimensional Self-Gravitating Systems
Tarcísio N. Teles, Yan Levin, Renato Pakter +1
We study, using both theory and molecular dynamics simulations, the relaxation dynamics of a microcanonical two dimensional self-gravitating system. After a sufficiently large time…
Relaxation and Emittance Growth of a Thermal Charged-Particle Beam
Tarcísio Nunes Teles, Renato Pakter, Yan Levin
We present a theory that allows us to accurately calculate the distribution functions and the emittance growth of a thermal charged-particle beam after it relaxes to equilibrium. T…
Collisionless relaxation in non-neutral plasmas
Yan Levin, Renato Pakter, Tarcisio N. Teles
A theoretical framework is presented which allows to quantitatively predict the final stationary state achieved by a non-neutral plasma during a process of collisionless relaxation…
