“…The thermal and magnetic properties due to electronic confinement have attracted significant interest such as electron-electron interaction on the energy spectrum [40] and electronic structure [41]. For instance, Atoyan et al [42] studied relativistic spinless particles in a 2D cylindrical potential. Gumber et al [43] studied a 3D cylindrical QD in the presence of external electric and magnetic field and went further to determine canonical partition function and other thermodynamic properties.…”

In this work, the thermodynamic property of pseudoharmonic potential in the presence of external magnetic and AB fields is investigated. We used effective Boltzmann factor within the superstatistics formalism to obtain the thermodynamic properties such as Helmholtz free energy (F), Internal energy (U), entropy(S) and specific heat (C) of the system. In addition, we discuss the result of the thermodynamic properties of some selected diatomic molecules of 2 2 2 ,, N Cl I and CH using their experimental spectroscopic parameters and that of the variation of the deformation parameter of 0,0.3,0.7 q  . We also illustrated with some graphs for clarity of our results in both cases.

“…Where the Nikiforov-Uvarov (NU) method is used to obtain exact eigenvalue and eigenfunctions. The potency of this method in obtaining exact analytical solutions is well documented in the sample of references (see, e.g., [6][7][8][39][40][41]). Such exact results collapse into those of the almost-quasi-free PDM-charged particles with m ( − → r ) = g (ρ) = η/ρ, of section 3, when V • = V 1 = V 2 = 0 = δ are used (this should be the natural tendency of the more general case, of course).…”

Using azimuthally symmetrized cylindrical coordinates, we consider some positiondependent mass (PDM) charged particles moving in position-dependent (PD) magnetic and Aharonov-Bohm flux fields. We focus our attention on PDM-charged particles with m ( − → r ) = g (ρ) = η f (ρ) exp (−δρ) (i.e., the PDM is only radially dependent) moving in an inverse power-law-type radial PD-magnetic fieldsUnder such settings, we consider two almost-quasi-free PDM-charged particles (i.e., no interaction potential, V ( − → r ) = 0) endowed with g (ρ) = η/ρ and g (ρ) = η/ρ 2 . Both yield exactly solvable Schrödinger equations of Coulombic nature but with different spectroscopic structures. Moreover, we consider a Yukawa-type PDM-charged particle with g (ρ) = η exp (−δρ) /ρ moving not only in the vicinity of the PD-magnetic and Aharonov-Bohm flux fields but also in the vicinity of a Yukawa plus a Kratzer type potential force field V (ρ) = −V• exp (−δρ) /ρ−V 1 /ρ+V 2 /ρ 2 . For this particular case, we use the Nikiforov-Uvarov (NU) method to come out with exact analytical eigenvalues and eigenfunctions. Which, in turn, recover those of the almost-quasi-free PDM-charged particle with g (ρ) = η/ρ for V• = V 1 = V 2 = 0 = δ.

“…Bockelman and Bastard studied interband absorption in quantum wires with and without magnetic field [18,19]. Direct interband light absorption in cylindrical quantum dot in quantizing magnetic field was studied by Atoyan et al [20]. Also nonlinear optical properties of a quantum wire with triangle cross section and V-groove quantum wire were studied in the reference [21,22].…”
