Weakly nonextensive thermostatistics and the Ising model with long–range interactions
We introduce a new nonextensive entropic measure Sχ that grows like N , where N is the size of the system under consideration. This kind of nonextensivity arises in a natural way in some N-body systems endowed with long-range interactions described by r−α interparticle potentials. The power law (weakly nonextensive) behavior exhibited by Sχ is intermediate between (1) the linear (extensive) reg...
متن کاملMagnetic properties of quantum Heisenberg ferromagnets with long-range interactions.
Quantum Heisenberg ferromagnets with long-range interactions in low dimensions are investigated by means of the Green’s function method. The model Hamiltonian is given by H = −(J0/2) ∑ i6=j r −p ij Si · Sj − H ∑ j S z j . It is shown that there exists a finite-temperature phase transition in the region d < p < 2d for the d-dimensional case and that no transitions at any finite temperature exist...
متن کاملFermi-Pasta-Ulam model with long-range interactions: Dynamics and thermostatistics
We study a long-range–interaction generalisation of the one-dimensional Fermi-PastaUlam (FPU) β-model, by introducing a quartic interaction coupling constant that decays as 1/r (α ≥ 0) (with strength characterised by b > 0). In the α → ∞ limit we recover the original FPU model. Through molecular dynamics we show that i) for α ≥ 1 the maximal Lyapunov exponent remains finite and positive for an ...
متن کاملNonlinear Wave Equations Related to Nonextensive Thermostatistics
We advance two nonlinear wave equations related to the nonextensive thermostatistical formalism based upon the power-law nonadditive Sq entropies. Our present contribution is in line with recent developments, where nonlinear extensions inspired on the q-thermostatistical formalism have been proposed for the Schroedinger, Klein–Gordon, and Dirac wave equations. These previously introduced equati...
متن کاملThermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet with long-range interactions via the spectral density method
The thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet, with long-range interactions decaying as r−p and in the presence of an external magnetic field, is investigated by means of the spectral density method in the framework of classical statistical mechanics. We find that long-range order exists at finite temperature for d < p < 2d with d ≤ 2 and for p > d with...
