Title:Vortices in Ginzburg-Landau Model of Superconductivity
Seminar:CCMA Luncheon Seminar
Speaker:Alex Misiats, Penn State University
Superconductivity is a complete loss of resistivity that occurs in most metals below a certain critical temperature. The key feature of this physical phenomenon is the vortices, or the points where the external magnetic field penetrates the bulk of a superconductor, thus destroying superconductivity. We model the superconducting vortices using the Ginzburg-Landau functional with a specific (degree) boundary condition that creates the same "quantized" vortices as the external magnetic field. In my talk I will discuss the issue of well-posedness of such modelling, which reduces to the question of the existence of minimizers for Ginzburg-Landau functional in certain functional classes. I will also address the vortex structure of Ginzburg-Landau minimizers.
