Bulk superconductivity in Type II superconductors near the second critical field
S. Fournais, B. Helffer
We consider superconductors of Type II near the transition from the 'bulk superconducting' to the 'surface superconducting' state. We prove a new estimate on the order…

Semiclassical reduction for magnetic Schroedinger operator with periodic zero-range potentials and applications
Bernard Helffer, Konstantin Pankrashkin
The two-dimensional Schroedinger operator with a uniform magnetic field and a periodic zero-range potential is considered. For weak magnetic fields we reduce the spectral problem t…
