Strong Coupling Asymptotics for Schrödinger Operators with an Interaction Supported by an Open Arc in three Dimensions

Result description

We consider Schrodinger operators with a strongly attractive singular interaction supported by a finite curve Gamma of length L in R-3. We show that if Gamma is C-4-smooth and has regular endpoints, the j-th eigenvalue of such an operator has the asymptotic expansion lambda(j)(H-alpha,H-Gamma) = xi(alpha)+lambda(j)(S)+O(e(pi alpha)) as the coupling parameter alpha -> -infinity, where xi(alpha)= -4 e(2)(-2 pi alpha+psi(1)) and lambda(j)(S) is the j-th eigenvalue of the Schrodinger operator S = -d(2)/ds(2) - 1/4 gamma(2)(s) on L-2(0, L) with Dirichlet condition at the interval endpoints in which gamma is the curvature of Gamma.
