Planar Dirac equation with radial contact potentials
J. T. Lunardi, S. Salamanca, J. Negro +1
We investigate the planar Dirac equation with the most general time-independent contact (singular) potential supported on a circumference. Taking advantage of the radial symmetry,…

Demkov-Fradkin tensor for curved harmonic oscillators
Şengül Kuru, Javier Negro, Sergio Salamanca
In this work, we obtain the Demkov-Fradkin tensor of symmetries for the quantum curved harmonic oscillator in a space with constant curvature given by a parameter . In order to…

Factorization Way to Symmetries of Systems on Curved Spaces
Sergio Salamanca
In a previous work we showcased the factorization method to find the symmetries of superintegrable systems with spherical separability in flat spaces. Here we analyze the same prob…
