Ginzburg-Landau-Gor’kov theory of magnetic oscillations in a type-II two-dimensional superconductor

Ginzburg-landau Theory of Vortex Phase Diagram in Layered Type Ii Superconductor

Various macroscopic phenomena seen in high temperature superconductors (HTSC) under nonzero magnetic fields have inspired much interest in studying the phase diagram of vortex states of three dimensional (3D) layered type II superconductors. Experimentally, thermodynamic and transport phenomena have been intensively examined mainly in YBCO [1-3] and BSCCO [4]. The resistive broadening [5] in th...

The Ginzburg-Landau Theory of Type II superconductors in magnetic field

Thermodynamics of type II superconductors in electromagnetic field based on the Ginzburg Landau theory is presented. The Abrikosov flux lattice solution is derived using an expansion in a parameter characterizing the ”distance” to the superconductor normal phase transition line. The expansion allows a systematic improvement of the solution. The phase diagram of the vortex matter in magnetic fie...

Justification of a two dimensional evolutionary Ginzburg-Landau superconductivity model

It is proved that a two dimensional evolutionary Ginzburg-Landau superconductivity model is an approximation of acorresponding thin plate three dimensional superconductivity model when the thickness of the plate uniformly approaches zero Some relatedtopics such as existence ofweak solutions to the three dimensional variable thickness model and the convergence when the variable thickness...

(0,2) Landau-ginzburg Theory ⋆

A large class of (0,2) Calabi-Yau σ-models and Landau-Ginzburg orbifolds are shown to arise as different “phases” of supersymmetric gauge theories. We find a phenomenon in the Landau-Ginzburg phase which may enable one to understand which Calabi-Yau σ-models evade destabilization by worldsheet instantons. Examples of (0,2) LandauGinzburg vacua are analyzed in detail, and several novel features ...
