Note on 2D Schrödinger operators with delta-interactions on angles and crossing lines
Vladimir Lotoreichik
In this note we sharpen the lower bound from [LLP10] on the spectrum of the 2D Schroedinger operator with a delta-interaction supported on a planar angle. Using the same method we…

Schrödinger operators with delta and delta'-potentials supported on hypersurfaces
Jussi Behrndt, Matthias Langer, Vladimir Lotoreichik
Self-adjoint Schrödinger operators with and -potentials supported on a smooth compact hypersurface are defined explicitly via boundary conditions. The spectral properties o…
