Domain Growth in Long-range Ising Models with Disorder
Ramgopal Agrawal, Federico Corberi, Eugenio Lippiello +1
Recent advances have highlighted the rich low-temperature kinetics of the long-range Ising model (LRIM). This study investigates domain growth in an LRIM with quenched disorder, fo…
Generalized Pearson distributions for charged particles interacting with an electric and/or a magnetic field
A. Rossani, A. M. Scarfone
The linear Boltzmann equation for elastic and/or inelastic scattering is applied to derive the distribution function of a spatially homogeneous system of charged particles spreadin…
Asymptotic solutions of a nonlinear diffusive equation in the framework of -generalized statistical mechanics
T. Wada, A. M. Scarfone
The asymptotic behavior of a nonlinear diffusive equation obtained in the framework of the -generalized statistical mechanics is studied. The analysis based on the classical Lie…
Fractal geometry of Ising magnetic patterns: signatures of criticality and diffusive dynamics
E. Agliari, R. Burioni, D. Cassi +1
We investigate the geometric properties displayed by the magnetic patterns developing on a two-dimensional Ising system, when a diffusive thermal dynamics is adopted. Such a dynami…
Two-dimensional one-component plasma on a Flamm's paraboloid
Riccardo Fantoni, Gabriel Tellez
We study the classical non-relativistic two-dimensional one-component plasma at Coulomb coupling Gamma=2 on the Riemannian surface known as Flamm's paraboloid which is obtained fro…
Instanton Solution of a Nonlinear Potential in Finite Size
Marco Zoli
The Euclidean path integral method is applied to a quantum tunneling model which accounts for finite size () effects. The general solution of the Euler Lagrange equation for the…
Lattice Boltzmann method for inhomogeneous fluids
S. Melchionna, U. Marini Bettolo Marconi
We present a lattice-based numerical method to describe the non equilibrium behavior of a simple fluid under non-uniform spatial conditions. The evolution equation for the one-part…
Long-time tails in sheared fluids
Michio Otsuki, Hisao Hayakawa
The long-time behaviors of the velocity autocorrelation function for sheared fluids ^M are investigated theoretically and numerically. It is found the existence of the cross…
Extracting signatures of quantum criticality in the finite-temperature behavior of many-body systems
Alessandro Cuccoli, Alessio Taiti, Ruggero Vaia +1
We face the problem of detecting and featuring footprints of quantum criticality in the finite-temperature behavior of quantum many-body systems. Our strategy is that of comparing…
Basic-deformed thermostatistics
A. Lavagno, A. M. Scarfone, P. Narayana Swamy
Starting from the basic-exponential, a q-deformed version of the exponential function established in the framework of the basic-hypergeometric series, we present a possible formula…
Gibbs States and the Set of Solutions of Random Constraint Satisfaction Problems
Florent Krzakala, Andrea Montanari, Federico Ricci-Tersenghi +2
An instance of a random constraint satisfaction problem defines a random subset S (the set of solutions) of a large product space (the set of assignments). We consider two prototyp…
Phase behavior of polydisperse sticky hard spheres: analytical solutions and perturbation theory
Domenico Gazzillo, Achille Giacometti, Riccardo Fantoni
We discuss phase coexistence of polydisperse colloidal suspensions in the presence of adhesion forces. The combined effect of polydispersity and Baxter's sticky-hard-sphere (SHS) p…
Quantum phase transition in spin systems studied through entanglement estimators
Andrea Fubini, Stephan Haas, Tommaso Roscilde +2
Entanglement represents a pure quantum effect involving two or more particles. Spin systems are good candidates for studying this effect and its relation with other collective phen…
Divergence of the entanglement range in low dimensional quantum systems
L. Amico, F. Baroni, A. Fubini +3
We study the pairwise entanglement close to separable ground states of a class of one dimensional quantum spin models. At T=0 we find that such ground states separate regions, in t…
Critical and tricritical singularities of the three-dimensional random-bond Potts model for large
M. T. Mercaldo, J-Ch. Anglès d'Auriac, F. Iglói
We study the effect of varying strength, , of bond randomness on the phase transition of the three-dimensional Potts model for large . The cooperative behavior of the system…
Legendre structure of the thermostatistics theory based on the Sharma-Taneja-Mittal entropy
A. M. Scarfone
The statistical proprieties of complex systems can differ deeply for those of classical systems governed by Boltzmann-Gibbs entropy. In particular, the probability distribution fun…
Critical behaviour of thin films with quenched impurities
L. Craco, L. De Cesare, I. Rabuffo +2
The critical behaviour of thin films containing quenched random impurities and inhomogeneities is investigated by the renormalization-group method. The finite-size crossover in imp…
Two generalizations of the Boltzmann equation
T. S. Biro, G. Kaniadakis
We connect two different generalizations of Boltzmann's kinetic theory by requiring the same stationary solution. Non-extensive statistics can be produced by either using correspon…
Classical q-deformed dynamics
A. Lavagno, A. M. Scarfone, P. Narayana Swamy
On the basis of the quantum q-oscillator algebra in the framework of quantum groups and non-commutative q-differential calculus, we investigate a possible q-deformation of the clas…
Canonical partition function for anomalous systems described by the -entropy
A. M. Scarfone, T. Wada
Starting from the -distribution function, obtained by applying the maximal entropy principle to the -entropy [G. Kaniadakis, Phys. Rev. E 66 (2002), 056125], we derive the ex…

On the basis of the recently proposed formalism [A. Lavagno and P.N. Swamy, Phys. Rev. E 65, 036101 (2002)], we show that the realization of the thermostatistics of q-deformed alge…
Renewal, Modulation and Superstatistics
Paolo Allegrini, Francesco Barbi, Paolo Grigolini +1
We consider two different proposals to generate a time series with the same non-Poisson distribution of waiting times, to which we refer to as renewal and modulation. We show that,…
