Nonsingular parametric oscillators Darboux-related to the classical harmonic oscillator
H. C. Rosu, O. Cornejo-Perez, P. Chen
Interesting nonsingular parametric oscillators which are Darboux related to the classical harmonic oscillator and have periodic dissipative/gain features are identified through a m…

Integrable dissipative nonlinear second order differential equations via factorizations and Abel equations
Stefan C. Mancas, Haret C. Rosu
We emphasize two connections, one well known and another less known, between the dissipative nonlinear second order differential equations and the Abel equations which in its first…

An alternative factorization of the quantum harmonic oscillator and two-parameter family of self-adjoint operators
R. Arcos-Olalla, M. A. Reyes, H. C. Rosu
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 harmoni…
