Eigensolution, expectation values and thermodynamic properties of the screened Kratzer potential

Improved multiparameter exponential‐type potential for diatomic molecules

“…An outlook from Figure shows that the improved MPETP performs better than the Morse potential in reproducing the internuclear potential curve for the X 2 ∑ + state of CP. The improved MPETP may be applied in dealing with other issues such as calculations of the Shannon entropy, Fisher information and thermodynamics properties for real molecular systems …”

Thermodynamic properties of improved deformed exponential-type potential (IDEP) for some diatomic molecules

“…These energy levels can be obtained using different techniques [16][17][18][19][20]. Different researchers have studied the thermodynamic properties of different potential functions for various systems [21][22][23].…”

Localization effect on Rényi complexity of Kratzer potential in the presence of Aharonov‐Bohm field

“…[ 2 ] The ring‐shaped Kratzer potential has been used to determine the noncentral ro‐vibrational energies and wave functions. In this article, we introduce the scalar potential as a sum of the Kratzer potential [ 1–40 ] and a θ ‐dependent potential V 1 ( θ ) in the form where D e , r , and r e are respectively the dissociation energy, the internuclear distance, and the equilibrium intermolecular separation between two diatomic molecules, and the Aharonov‐Bohm (AB) flux field [ 41–50 ] as a vector potential takes the form where ℱ is the flux created within a very thin and infinitely long solenoid along the z direction. [ 41,42 ] is called the flux quantum number, such that .…”

“…The ring‐shaped Kratzer potential has applications in ring‐shaped organic molecules such as cyclic polyenes and benzene. [ 6,9 ] In the field of quantum chemistry, we have found many papers of radial Kratzer [ 3,7,8,19,25,26,28,32–39 ] and single or double ring‐shaped Kratzer [ 11–17,27 ] potential in three dimensions [ 4,20,22–24,40 ] and multidimensions. [ 5,18,21,29–31 ] The exact solutions and spectrum analysis of the radial Schrödinger equation for Kratzer potential have been carried out a few years ago in the absence of the AB field.…”
