Uses a mean-field cluster model based on finite-size thermostatistics to extend the range of mean-field theory, thereby eliminating the need for a separate scaling regime. Use of a kinetic-energy term to maintain the microcanonical ensemble; Reproduction of the Curie-Weiss law at high temperatures; Transition which is mathematically similar to Bose-Einstein condensation that is yielded; Provision of a unified picture for both the critical-scaling and Curie-Weiss regimes.

    Mean-field theory and scaling arguments are presented to model polyelectrolyte adsorption from semidilute solutions onto charged surfaces. Using numerical solutions of the mean-field equations, we show that adsorption exists only for highly charged polyelectrolytes in low salt solutions. Simple...

    In the simple mean-field SIS and SIR epidemic models, infection is transmitted from infectious to susceptible members of a finite population by independent p-coin tosses. Spatial variants of these models are considered, in which finite populations of size N are situated at the sites of a lattice...

    A thermodynamic scaling law for the relaxation times of complex liquids as a function of temperature and volume has been proposed in the literature: τ(T,V) = ƒ(TVγ), where γ is a material-dependent constant. We test this scaling for six materials, linear polystyrene, star...

    We show that the structural relaxation time in supercooled fragile liquids obeys a scaling law over a large density-temperature domain. The extension of this scaling is also considered in the case of simulated liquid silica.

    We have considered a system where the interaction, v(r)=vIS(r)+ξ2vMF(r), is given as a linear combination of two potentials, each of which being characterized with a well-defined critical behavior: for vIS(r) we have chosen the potential of the restricted primitive model which is known to...

    The magnetofluctuation conductivity, called excess conductivity, originated from the forming of the superconducting droplet near to the mean-field transition temperature, was measured for the optimally doped BaFe1.8Co0.2As2 single crystals with a critical temperature, Tc, of 24.6 K. This...
