Description:

The aim of this workshop is to bring together mathematicians and physicists conducting research on models for superconductors, liquid crystals, micromagnetics, certain optical systems and thin films. The focus here will be on our ability to capture through these models the most interesting singular structures arising in these different contexts. Such structures include Ginzburg-Landau vortices, Bloch and Neel walls in micromagnetics, phase transition behavior in liquid crystals, optical singularities, folding patterns in thin film blisterings, etc.

Through the workshop, we hope to characterize the similarities and distinctions between these different structures and to compare the analytical tools available for the study of the different models. Emphasis will be placed on identifying physically interesting and mathematically tractable open problems in these areas.
