PT symmetric models in more dimensions and solvable square-well versions of their angular Schrödinger equations
نویسنده
چکیده
From the partial differential Calogero’s (three-body) and Smorodinsky-Winternitz (superintegrable) Hamiltonians in two variables we separate the respective angular Schrödinger equations and study the possibilities of their “minimal” PT symmetric complexification. The simultaneous loss of the Hermiticity and solvability of the respective angular potentials V (φ) is compensated by their replacement by solvable, purely imaginary and piece-wise constant multiple wells V0(φ). We demonstrate that the spectrum remains real and that it exhibits a rich “four series” structure in the double-well case.

On PT-symmetric extensions of the Calogero and Sutherland models
The original Calogero and Sutherland models describe N quantum particles on the line interacting pairwise through an inverse square and an inverse sinussquare potential. They are well known to be integrable and solvable. Here we extend the Calogero and Sutherland Hamiltonians by means of new interactions which are PT-symmetric but not self adjoint. Some of these new interactions lead to integra...
متن کاملExactly solvable models with PT −symmetry and with an asymmetric coupling of channels
Bound states generated by the K coupled PT −symmetric square wells are studied in a series of models where the Hamiltonians are assumed R−pseudo-Hermitian and R2−symmetric. Specific rotation-like generalized parities R are considered such that RN = I at some integers N . We show that and how our assumptions make the models exactly solvable and quasi-Hermitian. This means that they possess the r...
متن کاملComplex square well—a new exactly solvable quantum mechanical model
Recently, a class of PT -invariant quantum mechanical models described by the nonHermitian HamiltonianH = p2 + x2(ix) was studied. It was found that the energy levels for this theory are real for all > 0. Here, the limit as →∞ is examined. It is shown that in this limit, the theory becomes exactly solvable. A generalization of this Hamiltonian, H = p2 + x2M(ix) (M = 1, 2, 3, . . .) is also stud...
متن کاملSpontaneous breakdown of PT symmetry in the solvable square-well model
Apparently, the energy levels merge and disappear in many PT symmetric models. This interpretation is incorrect: In square-well model we demonstrate how the doublets of states in question continue to exist at complex conjugate energies in the strongly non-Hermitian regime.
