Title: The edge resonance in elastic media with zero Poisson coefficient

Abstract: A two-dimensional  elastic semistrip with stress-free boundary conditions and
zero Poisson coefficients has an embedded eigenvalue on top of the continuous spectrum.
This effect is known as edge resonance. For an infinite plate of finite thickness with a drilling
hole $(R^2\setminus\Omega)\times I$ actually infinitely many edge resonances will occur.
This is related to the spectral problem of perturbations of symbols with strongly degenerated
minima, which also appear in BCS theory. I give an overview on some of our results in this
area, which still poses a number of mathematical challenges.

Title: On the 3D Ginzburg-Landau model of superconductivity.

Abstract: The Ginzburg-Landau model is a phenomenological description of superconductivity. A crucial feature is the occurrence of vortices (similar to those in fluid mechanics, but quantized), which appear above a certain value of the applied magnetic field called the first critical field. We are interested in the regime of small ɛ, where ɛ>0 is the inverse of the Ginzburg-Landau parameter. In this regime, the vortices are at main order codimension 2 topological singularities.

In this talk I will present a quantitative 3D vortex approximation construction for the Ginzburg-Landau functional, which provides an approximation of vortex lines coupled to a lower bound for the energy, optimal to leading order, analogous to the 2D ones, and valid for the first time at the ɛ-level. I will then apply these results to describe the behavior of global minimizers for the 3D Ginzburg-Landau functional below and near the first critical field. I will also provide a quantitative product-type estimate for the study of Ginzburg-Landau dynamics.
