Transparent boundary conditions for the stationary Schroedinger equation via Weyl-Titchmarsh theory

V. A. Derkach, C. Trunk, J. R. Yusupov +1

We propose a general approach for deriving transparent boundary conditions for the stationary Schroedinger equation with arbitrary potential. It is proven that the transparent boun…

Operator based approach to PT-symmetric problems on a wedge-shaped contour

Florian Leben, Carsten Trunk

We consider a second-order differential equation $- y^{''} (z) - (i z)^{N + 2} y (z) = λ y (z), z \in Γ$ with an eigenvalue parameter $λ \in C$ . In $P T$ quantum mechanics…
