Unsuitable use of spin and pseudospin symmetries with a pseudoscalar Cornell potential
(Iop Publishing Ltd, 2014-09-01)
The concepts of spin and pseudospin symmetries has been used as mere rhetorics to decorate the pseudoscalar potential [Chin. Phys. B 22 090301 (2013)]. It is also pointed out that a more complete analysis of the bound ...

On higher spin symmetries in de Sitter QFTs
(2016-03-01)
We consider the consequences of global higher-spin symmetries in quantum field theories on a fixed de Sitter background of spacetime dimension D ≥ 3. These symmetries enhance the symmetry group associated with the isometries ...
Generalizing spin and pseudospin symmetries for relativistic spin 1/2 fermions
(Iop Publishing Ltd, 2016-01-01)
We propose a generalization of pseudospin and spin symmetries, the SU(2) symmetries of Dirac equation with scalar and vector mean-field potentials originally found independently in the 70's by Smith and Tassie, and Bell ...
Pseudospin and spin symmetries in 1+1 dimensions: the case of the Coulomb potential
(Elsevier B.V., 2015-05-01)
The problem of fermions in 1+1 dimensions in the presence of a pseudoscalar Coulomb potential plus a mixing of vector and scalar Coulomb potentials which have equal or opposite signs is investigated. We explore all the ...

Spin and pseudospin symmetries and the equivalent spectra of relativistic spin-1/2 and spin-0 particles
(2007-04-20)
We show that the conditions which originate the spin and pseudospin symmetries in the Dirac equation are the same that produce equivalent energy spectra of relativistic spin-1/2 and spin-0 particles in the presence of ...

We show that the conditions which originate the spin and pseudospin symmetries in the Dirac equation are the same that produce equivalent energy spectra of relativistic spin-1/2 and spin-0 particles in the presence of ...
Higher-spin initial data in twistor space with complex stargenvalues
(Springer, 2020-06)
This paper is a supplement to and extension of arXiv:1903.01399. In the internal twistor space of the 4D Vasiliev’s higher-spin gravity, we study the star-product eigenfunctions of number operators with generic complex ...
