  Thermodynamics properties of heavy mesons are calculated within the framework
of the N-dimensional radial Schrodinger equation. The Cornell potential is
extended by including the quadratic potential plus the inverse of quadratic
potential. The energy eigenvalues and the corresponding wave functions are
calculated in the N-dimensional space using the Nikiforov-Uvarov (NV) method.
The obtained results are applied for calculating the mass of spectra of
charmonium, bottomonium, bc, and cs mesons. The thermodynamics properties of
heavy quarkonia such as, the mean energy, specific heat, free energy, and
entropy are calculated. The effect of temperature and the dimensionality number
on heavy mesons masses and thermodynamics properties is investigated. The
obtained results are improved in comparison with other theoretical approaches
and in a good agreement with experimental data. We conclude that the present
potential well describes thermodynamic properties in the three-dimensional
space and also the higher dimensional space.
