Point Interactions: PT-Hermiticity and Reality of the Spectrum

量子物理 2007-05-23 v1

摘要

General point interactions for the second derivative operator in one dimension are studied. In particular, PT{\mathcal P \mathcal T}-self-adjoint point interactions with the support at the origin and at points ±l\pm l 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.
