Spectral asymptotics of a strong delta ' interaction on a planar loop
Original language description
We consider a generalized Schrodinger operator in L-2(R-2) with an attractive strongly singular interaction of delta ' type characterized by the coupling parameter beta > 0 and supported by a C-4 smooth closed curve Gamma of length L without self-intersections. It is shown that in the strong-coupling limit, beta -> 0(+), the number of eigenvalues behaves as 2L/pi beta + O(vertical bar ln beta vertical bar), and furthermore, that the asymptotic behavior of the jth eigenvalue in the same limit is -4/beta(2) + mu(j) + O(beta vertical bar ln beta vertical bar), where mu(j) is the jth eigenvalue of the Schrodinger operator on L-2(0, L) with periodic boundary conditions and the potential -1/4 gamma(2), where gamma is the signed curvature of Gamma.
