摘要
General point interactions for the second derivative operator in one dimension are studied. In particular, -self-adjoint point interactions with the support at the origin and at points are considered. The spectrum of such non-Hermitian operators is investigated and conditions when the spectrum is pure real are presented. The results are compared with those for standard self-adjoint point interactions.
