Behavior of the Feshbach-Villars oscillator (FVO) in Gürses space-time under Coulomb-type potential
Abdelmalek Bouzenada, Abdelmalek Boumali, Omar Mustafa +1
Our research aims to investigate how the gravitational field influences the spectroscopic structure of the Feshbach-Villars oscillator in Gürses space-time. To achieve this, we uti…
-weak-pseudo-Hermiticity generators and radially symmetric Hamiltonians
Omar Mustafa, S. Habib Mazharimousavi
A class of spherically symmetric non-Hermitian Hamiltonians and their η-weak-pseudo-Hermiticity generators are presented. An operators-based procedure is introduced so that the res…
Asymptotic solvability of an imaginary cubic oscillator with spikes
Miloslav Znojil, Frantisek Gemperle, Omar Mustafa
For the PT symmetric potential of Dorey, Dunning and Tateo we show that in the large angular momentum (i.e., strongly spiked) limit the low-lying eigenstates of this popular non-He…
