-invariant point interactions in one dimension
Abstract
By using Wu and Yu's pseudo-potential, we construct point interactions in one dimension that are complex but conform to space–time reflection invariance. The resulting point interactions are equivalent to those obtained by Albeverio, Fei and Kurasov as self-adjoint extensions of the kinetic energy operator.
