Thermal Properties and Quantum Information Theory with the Shifted Morse
Potential
Abstract
By employing the Nikiforov-Uvarov functional analysis (NUFA) method, we
solved the radial Schrodinger equation with the shifted Morse potential
model. The analytical expressions of the energy eigenvalues,
eigenfunctions and numerical results were determined for selected values
of the potential parameters. Variations of different thermodynamic
functions with temperature were discussed extensively. Different quantum
information theories including Shannon entropy, Fisher information and
Fisher-Shannon product of the shifted Morse potential were investigated
numerically and graphically in position and momentum spaces for ground
and first excited states. The quantum information theories considered
satisfied their corresponding inequalities including
Bialynicki–Birula–Mycielski, Stam–Cramer–Rao inequalities and the
Fisher–Shannon product relation.
