    "abstract": "In a PT symmetrically complexified square well, bound states are constructed\nby the matching technique. Their energies prove real in a domain of weak\nnon-Hermiticity, and continuous in the Hermitian limit. At a sequence of\ncertain strong-Hermiticity thresholds, the lowest two energies merge and\ndisappear.",
