Analytic solutions for Baxter's model of sticky hard sphere fluids within closures different from the Percus_Yevick approximation
Domenico Gazzillo, Achille Giacometti
We discuss structural and thermodynamical properties of Baxter's adhesive hard sphere model within a class of closures which includes the Percus-Yevick (PY) one. The common feature…
Lattice density-functional theory of surface melting: the effect of a square-gradient correction
S. Prestipino
I use the method of classical density-functional theory in the weighted-density approximation of Tarazona to investigate the phase diagram and the interface structure of a two-dime…
Anomalous dynamics of confined water at low hydration
P. Gallo, M. Rovere
The mobility of water molecules confined in a silica pore is studied by computer simulation in the low hydration regime, where most of the molecules reside close to the hydrophilic…
Generic features of the fluctuation dissipation relation in coarsening systems
Federico Corberi, Claudio Castellano, Eugenio Lippiello +1
The integrated response function in phase-ordering systems with scalar, vector, conserved and non conserved order parameter is studied at various space dimensionalities. Assuming s…
Slow dynamics of a confined supercooled binary mixture II: Q space analysis
P. Gallo, R. Pellarin, M. Rovere
We report the analysis in the wavevector space of the density correlator of a Lennard Jones binary mixture confined in a disordered matrix of soft spheres upon supercooling. In spi…
Non trivial behavior of the linear response function in phase ordering kinetics
Federico Corberi, Nicola Fusco, Eugenio Lippiello +1
Drawing from exact, approximate and numerical results an overview of the properties of the out of equilibrium response function in phase ordering kinetics is presented. Focusing on…
Defining and identifying communities in networks
Filippo Radicchi, Claudio Castellano, Federico Cecconi +2
The investigation of community structures in networks is an important issue in many domains and disciplines. This problem is relevant for social tasks (objective analysis of relati…
Direct correlation functions of the Widom-Rowlinson model
R. Fantoni, G. Pastore
We calculate, through Monte Carlo numerical simulations, the partial total and direct correlation functions of the three dimensional symmetric Widom-Rowlinson mixture. We find that…
Modulational Instability and Complex Dynamics of Confined Matter-Wave Solitons
L. Salasnich, A. Parola, L. Reatto
We study the formation of bright solitons in a Bose-Einstein condensate of Li atoms induced by a sudden change in the sign of the scattering length from positive to negative, a…
Statistical mechanics of the majority game
P. Kozlowski, M. Marsili
The majority game, modelling a system of heterogeneous agents trying to behave in a similar way, is introduced and studied using methods of statistical mechanics. The stationary st…
When does coarsening occur in the dynamics of one-dimensional fronts ?
Paolo Politi, Chaouqi Misbah
Dynamics of a one-dimensional growing front with an unstable straight profile are analyzed. We argue that a coarsening process occurs if and only if the period λof the steady state…
Density-functional theory of a lattice-gas model with vapour, liquid, and solid phases
S. Prestipino, P. V. Giaquinta
We use the classical version of the density-functional theory in the weighted-density approximation to build up the entire phase diagram and the interface structure of a two-dimens…
The concavity of entropy and extremum principles in thermodynamics
S. Prestipino, P. V. Giaquinta
We revisit the concavity property of the thermodynamic entropy in order to formulate a general proof of the minimum energy principle as well as of other equivalent extremum princip…
Low-Temperature Quantum Critical Behaviour of Systems with Transverse Ising-like Intrinsic Dynamics
A. Caramico D'Auria, L. De Cesare, I. Rabuffo
The low-temperature properties and crossover phenomena of -dimensional transverse Ising-like systems within the influence domain of the quantum critical point are investigated s…

S. Prestipino
Elaborating on previous theoretical treatments of the roughening transition, we provide the exact mapping of a surface model which undergoes both roughening and preroughening onto…
Thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet with long-range interactions via the spectral density method
A. Cavallo, F. Cosenza, L. De Cesare
The thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet, with long-range interactions decaying as and in the presence of an external magnet…

Laszlo Granasy, Tamas Pusztai, Zoltan Jurek +2
The phase field theory of crystal nucleation described in [L. Granasy, T. Borzsonyi, T. Pusztai, Phys. Rev. Lett. 88, 206105 (2002)] is applied for nucleation in hard--sphere liqui…
Spectral Statistics of the Triaxial Rigid Rotator: Semiclassical Origin of their Pathological Behavior
V. R. Manfredi, V. Penna, L. Salasnich
In this paper we investigate the local and global spectral properties of the triaxial rigid rotator. We demonstrate that, for a fixed value of the total angular momentum, the energ…
Detection of XY behaviour in weakly anisotropic quantum antiferromagnets on the square lattice
Alessandro Cuccoli, Tommaso Roscilde, Ruggero Vaia +1
We consider the Heisenberg antiferromagnet on the square lattice with S=1/2 and very weak easy-plane exchange anisotropy; by means of the quantum Monte Carlo method, based on the c…
Beyond the Kolmogorov Johnson Mehl Avrami kinetics: inclusion of the spatial correlation
M. Fanfoni, M. Tomellini
The Kolmogorov-Johnson-Mehl-Avrami model, which is a nucleation and growth poissonian process in space, has been implemented by taking into account spatial correlation among nuclei…
