Generalised two-dimensional nonlinear oscillator with a position-dependent effective mass and the thermodynamic properties
S. E. Bokpe, F. A. Dossa, G. Y. H. Avossevou
We investigate a two-dimensional nonlinear oscillator with a position-dependent effective mass in the framework of nonrelativistic quantum mechanics. Using the Nikiforov-Uvarov met…
Algebraic solution and thermodynamic properties of graphene in the presence of minimal length
J. Gbètoho, F. A. Dossa, G. Y. H. Avossevou
Graphene is a zero-gap semiconductor, where the electrons propagating inside are described by the ultra-relativistic Dirac equation normally reserved for very high energy massless…
A remarkable dynamical symmetry of the Landau problem
Tekin Dereli, Philippe Nounahon, Todor Popov
We show that the dynamical group of an electron in a constant magnetic field is the group of symplectomorphisms . It is generated by the spinorial realization of…
Compact Cauchy horizons admit constant surface gravity
Raymond A. Hounnonkpe, Ettore Minguzzi
We prove that in any spacetime dimension and under the null energy condition, every totally geodesic connected smooth compact null hypersurface (hence every compact Cauchy horizon)…
Slow-roll Natural & Hilltop Inflation in Rastall Gravity
Isaac M. Vitohekpon, Biswajit Deb, Ines G. Salako +2
This study provides a concise analysis of inflation under Rastall gravity by examining three types of potential such as the power law, natural, and hilltop potentials. Choosing a m…
Eigensolutions and thermodynamic properties of generalized hyperbolic Hulthen and Woods-Saxon potential
Y. M. Assimiou, S. T. Daniel, G. Issoufou +2
In this paper, we present the solutions of the Schrödinger equation and the thermodynamic properties of generalized hyperbolic Hulthen and Woods-Saxon potential. The eigenvalues an…
