Two-parametric PT-symmetric quartic family
نویسندگان
چکیده
We describe a parametrization of the real spectral locus of the twoparametric family of PT-symmetric quartic oscillators. For this family, we find a parameter region where all eigenvalues are real, extending the results of Dorey, Dunning, Tateo and Shin. MSC: 81Q05, 34M60, 34A05

A perturbative treatment of a generalized PT -Symmetric Quartic Anharmonic Oscillator
We examine a generalized PT -symmetric quartic anharmonic oscillator model to determine the various physical variables perturbatively in powers of a small quantity ε.We make use of the Bender-Dunne operator basis elements and exploit the properties of the toatally symmetric operator Tm,n.
متن کاملThe S-matrix of the Faddeev-Reshetikhin Model, Diagonalizability and PT Symmetry
We study the question of diagonalizability of the Hamiltonian for the FaddeevReshetikhin (FR) model in the two particle sector. Although the two particle S-matrix element for the FR model, which may be relevant for the quantization of strings on AdS5×S, has been calculated recently using field theoretic methods, we find that the Hamiltonian for the system in this sector is not diagonalizable. W...
متن کامل-symmetric quartic anharmonic oscillator and position-dependent mass in a perturbative approach
To lowest order of perturbation theory we show that an equivalence can be established between a PT -symmetric generalized quartic anharmonic oscillator model and a Hermitian position-dependent mass Hamiltonian h. An important feature of h is that it reveals a domain of couplings where the quartic potential could be attractive, vanishing or repulsive. We also determine the associated physical qu...
