Asymptotic spectral analysis in colliding leaky quantum layers
Sylwia Kondej, David Krejcirik
We consider the Schroedinger operator with a complex delta interaction supported by two parallel hypersurfaces in the Euclidean space of any dimension. We analyse spectral properti…

Spectral asymptotics induced by approaching and diverging planar circles
Sylwia Kondej
We consider two dimensional system governed by the Hamiltonian with delta interaction supported by two concentric circles separated by distance . We analyze the asymptotics of t…
