General approach to potentials with two known levels
S. N. Dolya, O. B. Zaslavskii
We present the general form of potentials with two given energy levels , and find corresponding wave functions. These entities are expressed in terms of one function…

Quantum anharmonic oscillator and quasi-exactly solvable Bose systems
S. N. Dolya, O. B. Zaslavskii
We extend the notion of quasi-exactly solvable (QES) models from potential ones and differential equations to Bose systems. We obtain conditions under which algebraization of the p…
