Ginzburg-Landau Calculations of Circular Mo80Ge20 Plates with Sector Defect

Ramond Sector Characters and N=2 Landau–Ginzburg Models

We give a direct proof of the new ”product” expression for the Ramond sector characters of N=2 minimal models recently suggested by E. Witten. Our construction allows us to generalize these expressions to the D and E series of N=2 minimal models, as well as to other N=2 Kazama–Suzuki coset models such as SU(N)×SO(2(N−1))/SU(N−1)×U(1). We verify that these expressions indeed coincide with the co...

Defect statistics in the two-dimensional complex Ginzburg-Landau model.

The statistical correlations between defects in the two-dimensional complex Ginzburg-Landau model are studied in the defect-coarsening regime. In particular the defect-velocity probability distribution is determined and has the same high velocity tail found for the purely dissipative time-dependent Ginzburg-Landau (TDGL) model. The spiral arms of the defects lead to a very different behavior fo...

Defect–Defect Correlation Functions, Generic Scale Invariance, and the Complex Ginzburg–Landau Equation

We present a calculation of defect–defect correlation functions in the defect turbulence regime of the complex Ginzburg–Landau equation. Our results do not agree with the predictions of generic scale invariance. Using the topological nature of the defects, we prove that defect–defect correlations cannot decay as slowly as predicted by generic scale invariance Typeset using REVTEX 1 Spatiotempor...

(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 ...
