Solvability and -symmetry in a double-well model with point interactions
Solvability and -symmetry in a double-well model with point interactions
The concept of point interactions offers one of the most suitable guides towards a quantitative analysis of properties of certain specific non-Hermitian (so-called -symmetric) quantum-mechanical systems. This is illustrated with a double-well model, the easy solvability of which is shown to lead to a clear picture of the mechanisms of …
