    "abstract": "The original Jaynes-Cummings model is described by a Hamiltonian which is\nexactly solvable. Here we extend this model by several types of interactions\nleading to a nonhermitian operator which doesn\u0027t satisfy the physical condition\nof space-time reflection symmetry (PT symmetry). However the new Hamiltonians\nare either exactly solvable admitting an entirely real spectrum or quasi\nexactly solvable with a real algebraic part of their spectrum.",
