On the Ginzburg-Landau critical field in three dimensions
S. Fournais, B. Helffer
We study the three dimensional Ginzburg-Landau model of superconductivity. Several `natural' definitions of the (third) critical field, , governing the transition from the…

Accurate estimates for magnetic bottles in connection with superconductivity
S. Fournais, B. Helffer
Motivated by the theory of superconductivity and more precisely by the problem of the onset of superconductivity in dimension two, many papers devoted to the analysis in a semi-cla…

Zero energy asymptotics of the resolvent for a class of slowly decaying potentials
S. Fournais, E. Skibsted
We prove a limiting absorption principle at zero energy for two-body Schrödinger operators with long-range potentials having a positive virial at infinity. More precisely, we estab…
