An eigenvalue inequality for Schrödinger operators with and -interactions supported on hypersurfaces
Vladimir Lotoreichik, Jonathan Rohleder
We consider self-adjoint Schrödinger operators in with a -interaction of strength and a -interaction of strength , respectively, supported on a h…
Schrödinger operators with -interactions supported on conical surfaces
Jussi Behrndt, Pavel Exner, Vladimir Lotoreichik
We investigate the spectral properties of self-adjoint Schrödinger operators with attractive -interactions of constant strength supported on conical surfaces in ${\mathbb…
Spectral asymptotics for resolvent differences of elliptic operators with and -interactions on hypersurfaces
Jussi Behrndt, Gerd Grubb, Matthias Langer +1
We consider self-adjoint realizations of a second-order elliptic differential expression on with singular interactions of and -type supported on a com…
Weakly coupled bound state of 2D Schrödinger operator with potential-measure
Sylwia Kondej, Vladimir Lotoreichik
We consider a self-adjoint two-dimensional Schrödinger operator , which corresponds to the formal differential expression \[ -Δ- αμ, \] where is a finite compactly supp…
