Statistical mechanics of vortex systems in two-dimensional superconductors

Physical Review B, 1993
The thermodynamics of a two-dimensional vortex plasma in thin-film superconductors is described in the framework of a cycle approximation. The equation for the density of free vortices is obtained from the virial expansion. This equation provides a unified approach to describe both the Kosterlitz-Thouless-like behavior in the vicinity of the ...

Statistical mechanics of flux lines in high-T c superconductors

Journal of Statistical Physics, 1989
A theory of the entangled flux liquids which arise in the new high-Tc superconductors is reviewed. New physics appears because of the weak interplanar couplings and high critical temperatures in these materials. Flux line wandering melts the conventional Abrikosov flux lattice, and leads to an entangled vortex state whose statistical mechanics is ...

Quantum statistical mechanics of vortices in type II superconductors

Journal of Low Temperature Physics, 1994
We critically review recent developments in the quantum statistical mechanics and in the quantum dynamics of the vortex system in high temperature- and in conventional high-resistivity thin-film superconductors.

Vortices in high temperature superconductors: the statistical mechanics and dynamics of strings

Physica A: Statistical Mechanics and Its Applications, 1993
Abstract We briefly discuss a selection of the most pertinent features in the phenomenology of high temperature superconductors. We concentrate on the continuous anisotropic case with results appropriate for YBCO.

Statistical mechanics of vortex system in a thin-film superconductor in the ring approximation

Theoretical and Mathematical Physics, 1993
The statistical mechanics and thermodynamics of a two-dimensional system of vortices in a thin superconducting film are constructed. The long-range interaction of the vortices is taken into account in the ring approximation well known from plasma theory.

Statistical mechanics of flux lines in oxide superconductors

Physica A: Statistical Mechanics and its Applications, 1994
The structure of the unpinned vortex liquid in strongly anisotropic layered high-$T_c$ oxide superconductors in a magnetic field B perpendicular to the layer plane is investigated by using appropriate classical liquid-state theories. The direct correlation function so obtained is used as input for a parameter-free, first-principles calculation of the ...

A Statistical Mechanical Model of Critical Currents in Superconductors

Journal of Superconductivity and Novel Magnetism, 2013
We present a statistical mechanical model for critical currents which is successful in describing both the in-plane and out-of-plane magnetic field angle dependence of J c . This model is constructed using the principle of maximum entropy, that is, by maximizing the information entropy of a distribution,

Statistical mechanics of the local-pair superconductor: phase diagrams and specific heats

Journal of the Less Common Metals, 1990
Abstract The quantum-lattice-gas model, originally introduced by Matsubara and Matsuda to describe the superfluid properties of 4 He, relates the hamiltonian of a system of hard-core bosons hopping on a lattice with nearest-neighbour transfer integral t and interaction v , to that of a spin S = 1 2 , uniaxially anisotropic Heisenberg ...
