The radial supersymmetry of the (d+1)-dimensional relativistic rotating oscillators
Ion I. Cotăescu, jr
We study the supersymmetry of the radial problems of the models of quantum relativistic rotating oscillators in arbitrary dimensions, defined as Klein-Gordon fields in backgrounds…

The quantum modes of the (1+1)-dimensional oscillators in general relativity
Ion I. Cotăescu
The quantum modes of a new family of relativistic oscillators are studied by using the supersymmetry and shape invariance in a version suitable for (1+1) dimensional relativistic s…

Comment on the quantum modes of the scalar field on AdS_{d+1} spacetime
Ion I. Cotăescu
The problem of the quantum modes of the scalar free field on anti-de Sitter backgrounds with an arbitrary number of space dimensions is considered. It is shown that this problem ca…
