Energy spectrum inverse problem of q-deformed harmonic oscillator and WBK approximation

Nguyen Anh Sang, Do Thi Thu Thuy, Nguyen Thi Ha Loan, Nguyen Tri Lan and Nguyen Ai Viet

Using the connection between q-deformed harmonic oscillator and Morse–like anharmonic potential we investigate the energy spectrum inverse problem. Consider some energy levels of energy spectrum of q–deformed harmonic oscillator are known, we construct the corresponding Morse-like potential then find out the deform parameter q. The application possibility of using the WKB approximation in the energy spectrum inverse problem was discussed for the cases of parabolic potential (harmonic oscillator), Morse–like potential (q–deformed harmonic oscillator). so we consider our deformed–three–levels simple model, where the set–parameters of Morse potential and the corresponding set–parameters of level deformations are easily and explicitly defined. For practical problems, we propose the deformedthree-levels simple model, where the set–parameters of Morse potential and the corresponding set-parameters of level deformations are easily and explicitly defined.
