Quantum information entropies for a soliton at hyperbolic well

Abstract

In this work, the probability uncertainties related to a stationary quantum system with solitonic mass distribution when subjected to deformable hyperbolic potentials are studied. Shannon's entropy and Fisher's information of a position-dependent mass are calculated. To investigate the concept of Shannon and Fisher entropies of the solitonic mass distribution subject to the hyperbolic potential, it is necessary to obtain the analytic solutions at position and momentum space. For the Hamiltonian operator to be Hermitian, we consider the stationary Schr\"odinger equation ordered by Zhu-Kroemer. This ordering is known to describe abrupt heterojunctions in semiconductor materials.
