Non-Gaussian equilibrium in a long-range Hamiltonian system.

چکیده
We study the dynamics of a system of N classical spins with infinite-range interaction. We show that, if the thermodynamic limit is taken before the infinite-time limit, the system does not relax to the Boltzmann-Gibbs equilibrium, but exhibits different equilibrium properties, characterized by stable non-Gaussian velocity distributions, Lévy walks, and dynamical correlation in phase space.

Fingerprints of nonextensive thermodynamics in a long-range Hamiltonian system
We study the dynamics of a Hamiltonian system of N classical spins with infiniterange interaction. We present numerical results which confirm the existence of metaequilibrium Quasi Stationary States (QSS), characterized by non-Gaussian velocity distributions, anomalous diffusion, Lévy walks and dynamical correlation in phase-space. We show that the Termodynamic Limit (TL) and the Infinite-Time ...
متن کاملDynamics and Thermodynamics of a model with long-range interactions
The dynamics and the thermodynamics of particles/spins interacting via long-range forces display several unusual features with respect to systems with shortrange interactions. The Hamiltonian Mean Field (HMF) model, a Hamiltonian system of N classical inertial spins with infinite-range interactions represents a paradigmatic example of this class of systems. The equilibrium properties of the mod...
متن کاملEquilibration in the Nosé-Hoover Isokinetic Ensemble: Effect of Inter-Particle Interactions
We investigate the stationary and dynamic properties of the celebrated Nosé-Hoover 1 dynamics of many-body interacting Hamiltonian systems, with an emphasis on the effect of 2 inter-particle interactions. To this end, we consider a model system with both shortand long-range 3 interactions. The Nosé-Hoover dynamics aims to generate the canonical equilibrium distribution 4 of a system at a desire...
متن کاملNon-extensive Entropy and Quasi-Equilibrium States in Hamiltonian Mean-Field Model
We investigate the thermodynamic properties of Hamiltonian mean-field(HMF) model as a prototypical long-range system by means of the non-extensive thermostatistics. Especially, the quasi-equilibrium state as extremum state of the generalized Tsallis entropy is studied and its thermodynamic stability is analyzed. Based on these analysis, the connection with quasi-stationary behaviors found in th...
متن کاملAn extended complete Chebyshev system of 3 Abelian integrals related to a non-algebraic Hamiltonian system
In this paper, we study the Chebyshev property of the 3-dimentional vector space $E =langle I_0, I_1, I_2rangle$, where $I_k(h)=int_{H=h}x^ky,dx$ and $H(x,y)=frac{1}{2}y^2+frac{1}{2}(e^{-2x}+1)-e^{-x}$ is a non-algebraic Hamiltonian function. Our main result asserts that $E$ is an extended complete Chebyshev space for $hin(0,frac{1}{2})$. To this end, we use the criterion and tools developed by...
