Information-theoretic measures for a position-dependent mass system in an infinite potential well
Abstract
In this work we calculate the Cram\'er-Rao, the Fisher-Shannon and the L\'opez-Ruiz-Mancini-Calbert (LMC) complexity measures for eigenstates of a deformed Schr\"odinger equation, being this intrinsically linked with position-dependent mass (PDM) systems. The formalism presented is illustrated with a particle confined in an infinite potential well. Abrupt variation of the complexity near to the asymptotic value of the PDM-function m(x) and erasure of its asymmetry along with negative values of the entropy density in the position space, are reported as a consequence of the interplay between the deformation and the complexity.
