    "abstract": "A variational calculation of the energy levels of a class of PT-invariant\nquantum mechanical models described by the non-Hermitian Hamiltonian H= p^2 -\n(ix)^N with N positive and x complex is presented. Excellent agreement is\nobtained for the ground state and low lying excited state energy levels and\nwave functions. We use an energy functional with a three parameter class of\nPT-symmetric trial wave functions in obtaining our results.",
