Hulthen plus Hellmann potentials are adopted as the quark–antiquark interaction potential for studying thermodynamic properties and mass spectra of heavy mesons. The was rendered temperature dependent by replacing screening parameter with Debye mass. We solved radial Schrödinger equation analytically using Nikiforov–Uvarov method. energy eigenvalues corresponding wave function in terms Laguerre...

In many fields of physics and chemistry, explicit analytical solutions of the fundamental dynamical equations are much valuable for a general understanding of phenomena, e. g. the role played by physical parameters. Two typical examples in quantum mechanics are the exact solutions of the Schrödinger equation (SE) for a hydrogen atom (Coulombic) and for a harmonic oscillator [1 – 3]. The Mie-typ...

Keywords: Dirac equation Yukawa potential Coulomb-like tensor potential Spin and p-spin symmetry Nikiforov–Uvarov method a b s t r a c t This study presents the solutions of the Dirac equation with a new suggested Yukawa-type potential for any spin–orbit quantum number j interacting with a Coulomb-like tensor interaction. In the presence of spin and pseudospin (p-spin) symmetries, the approxima...

We solve the Schrödinger equation for a charged particle in non-uniform magnetic field by using Nikiforov–Uvarov method. find energy spectrum and wave function, present an explicit relation partition function. give analytical expressions thermodynamic properties such as mean susceptibility, analyze entropy, free specific heat of this system numerically. It is concluded that susceptibility incre...
