    "abstract": "The simplest purely imaginary and piecewise constant $\\cal PT$-symmetric\npotential located inside a larger box is studied. Unless its strength exceeds a\ncertain critical value, all the spectrum of its bound states remains real and\ndiscrete. We interpret such a model as an initial element of the generalized\nnon-Hermitian Witten\u0027s hierarchy of solvable Hamiltonians and construct its\nfirst supersymmetric (SUSY) partner in closed form.",
