Complex energy spectra in reggeon quantum mechanics with cubic plus generalized quartic interactions

Nuclear Physics B, 1981
Abstract We investigate the energy eigenvalue spectra in reggeon quantum mechanics when the hamiltonian contains (non-hermitian) cubic, symmetric quartic and asymmetric quartic interactions. We describe two new methods for finding eigenvalues numerically.
