Entropy and and Information of a harmonic oscillator in a time-varying electric field in 2D and 3D noncommutative spaces

We analyze the noncommutativity effects on the Fisher information (F-(r) over cap,((p) over cap)) and Shannon entropies (S-(r) over cap,((p) over cap)) of a harmonic oscillator immersed in a time-varying electric field in two and three dimensions. We find the exact solutions of the respective time-dependent Schrodinger equation and use them to calculate the Fisher information and the Shannon entropy for the simplest case corresponding to the lowest-lying state of each system. While there is no problem in defining the Shannon entropy for noncommutating spaces, the definition of the Fisher information have to be modified to satisfy the Cramer-Rao inequalities. For both systems we observe how the Fisher information and Shannon entropy in position and momentum change due to the noncommutativity of the space. We verify that the Bialynicki-Birula-Mycielski (BBM) entropic uncertainty relation still holds in the systems considered. (C) 2017 Elsevier B.V. All rights reserved.
