A new approach to one-dimensional oscillators in relativistic quantum mechanics. (English) Zbl 1312.81064

Summary: A new approach to the one-dimensional oscillatory motion of a relativistic quantum particle with the spin \(1/2\) is presented. It is based on a modified form of the Hamilton operator of the particle. As particular cases, the one-dimensional Dirac oscillator and the one-dimensional oscillator with equidistant energy levels are discussed. In this context, the first oscillator appears as an ancient representative, while the second oscillator is a new representative of an entire class of relativistic quantum one-dimensional oscillators.
