Abstract
New non Hermitian Hamiltonians are generated, as isospectral partners of the generalized Swanson model, viz., , where are real constants, with , and and are generalized creation and annihilation operators. It is shown that the initial Hamiltonian , and its partner , are related by pseudo supersymmetry, and they share all the eigen energies except for the ground state. This pseudo supersymmetric extension enlarges the class of non Hermitian Hamiltonians , related to their respective Hermitian counterparts , through the same similarity transformation operator : . The formalism is applied to the entire class of shape-invariant models.
