Electrostatic Potential in High-Temperature Superconducting Cuprates: Extended Ginzburg-Landau Theory

(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 ...

Superconductivity: Ginzburg-Landau Theory

Landau Ginzburg Theory and Nuclear Matter at Finite Temperature

Based on recent studies of the temperature dependence of the energy and specific heat of liquid nuclear matter, a phase transition is suggested at a temperature ∼ .8 MeV. We apply Landau Ginzburg theory to this transition and determine the behaviour of the energy and specific heat close to the critical temperature in the condensed phase. The existence of an energy gap in the spectrum of even-ev...

Fluctuations in Superconductors using Landau-Ginzburg Theory

In this paper, we study the fluctuations in superconductors in the framework of Landau-Ginzurg theory. First, we review the formulation of LG theory and derive the LG equations. The we calculate the fluctuation contribution to the saddle point heat capacity, both inside and outside the immediate vicinity of the transition point. Outside the immediate vicinity, we follow the Gaussian integral ca...
