The Schr\" odinger picture of the Dirac quantum mechanics on spatially flat Robertson-Walker backgrounds
Ion I. Cotaescu
The Schr\" odinger picture of the Dirac quantum mechanics is defined in charts with spatially flat Robertson-Walker metrics and Cartesian coordinates. The main observables of this…

Pseudo-Gaussian quantum models
Ion I. Cotaescu
A new family of one-dimensional quantum models is proposed in terms of new potentials with a Gaussian asymptotic behavior but approaching to the potential of the harmonic o scillat…

Infinite loop superalgebras of the Dirac theory on the Euclidean Taub-NUT space
Ion I. Cotaescu, Mihai Visinescu
The Dirac theory in the Euclidean Taub-NUT space gives rise to a large collection of conserved operators associated to genuine or hidden symmetries. They are involved in interestin…
