    "abstract": "A purely imaginary potential can provide a phenomenological description of\ncreation and absorption of quantum mechanical particles. PT-invariance of such\na potential ensures that the non-unitary phenomena occur in a balanced manner.\nIn spite of wells and sinks which locally violate the conservation of quantum\nprobability, there is no net get loss or gain of particles. This, in turn, is\nintuitively consistent with real energy eigenvalues.",
