An alternative factorization of the quantum harmonic oscillator and two-parameter family of self-adjoint operators
2012
Abstract We introduce an alternative factorization of the Hamiltonian of the quantum harmonic oscillator which leads to a two-parameter self-adjoint operator from which the standard harmonic oscillator, the one-parameter oscillators introduced by Mielnik, and the Hermite operator are obtained in certain limits of the parameters. In addition, a single Bernoulli-type parameter factorization, which is different from the one introduced by M.A. Reyes, H.C. Rosu, and M.R. Gutierrez [Phys. Lett. A 375 (2011) 2145], is briefly discussed in the final part of this work.
