Spectral asymptotics of a strong delta ' interaction supported by a surface
We derive asymptotic expansion for the spectrum of Hamiltonians with a strong attractive delta' interaction supported by a smooth surface in R-3, either infinite and asymptotically planar, or compact and closed. Its second ...

Asymptotics of eigenvalues of the Schrodinger operator with a strong delta-interaction on a loop.
In this paper we investigate the operator H-beta = -Delta - betadelta((.) - Gamma) in L-2(R-2), where beta > 0 and Gamma is a closed C-4 Jordan curve in R-2. We obtain the asymptotic form of each eigenvalue of H-beta as beta tends to infinit...

Band gap of the Schrodinger operator with a strong delta-interaction on a periodic curve
In this paper we study the operator H-beta = -Delta - betadelta((.) - Gamma) in L-2(R-2), where Gamma is a smooth periodic curve in R-2. We obtain the asymptotic form of the band spectrum of H-beta as beta tends to infinity. Furthermore, we ...

Strong-coupling asymptotic expansion for Schrodinger operators with a singular interaction supported by a curve in R-3
We investigate a class of generalized Schrodinger operators in L-2(R-3) with a singular interaction supported by a smooth curve Gamma. We find a strong-coupling asymptotic expansion of the discrete spectrum in the case when Gamma is...

Scattering by local deformations of a straight leaky wire
We consider a model of a leaky quantum wire with the Hamiltonian -Delta - alpha delta(x - Gamma) in L-2(R-2), where Gamma is a compact deformation of a straight line. The existence of wave operators is proven and the S-matrix is fou...
