dc.description.abstractWe study the problem of locating spectral singularities of a general complex point interaction with a support at a single point. We also determine the bound states, examine the special cases where the point interaction is P-, T- and PT- symmetric, and explore the issue of the coalescence of spectral singularities and bound states.
