Title: Microscopic derivation of the Ginzburg-Landau model
I will discuss how the Ginzburg-Landau model of
superconductivity arises as an asymptotic limit of the microscopic
Bardeen-Cooper-Schrieffer (BCS) model. The asymptotic limit may be seen as
a semiclassical limit and one of the main difficulties is to derive a
semiclassical expansion with minimal regularity assumptions.
