Information analysis in free and confined harmonic oscillator
Neetik Mukherjee, Amlan K. Roy
In this chapter we shall discuss the recent progresses of information theoretic tools in the context of free and confined harmonic oscillator. Confined quantum systems have provide…
Analysis of Compton profile through information theory in H-like atoms inside impenetrable sphere
Neetik Mukherjee, Amlan K. Roy
Confinement of atoms inside various cavities has been studied for nearly eight decades. However, the Compton profile for such systems has not yet been investigated. Here we constru…
Shannon entropy in confined He-like ions within a density functional formalism
Sangita Majumdar, Amlan K. Roy
Shannon entropy in position ($S_{\rvec}$) and momentum ($S_{\pvec}$) spaces, along with their sum () are presented for unit-normalized densities of He, Li and Be io…
A general method for central potentials in quantum mechanics
Amlan K. Roy
We focus on a recently developed generalized pseudospectral method for accurate, efficient treatment of certain central potentials of interest in various branches in quantum mechan…
Information entropy and complexity measure in generalized Kratzer potential
Sangita Majumdar, Neetik Mukherjee, Amlan K. Roy
Shannon entropy (), Fisher information () and a measure equivalent to Fisher-Shannon complexity of a ro-vibrational state of diatomic molecules (O, O, NO…
Fisher information in confined isotropic harmonic oscillator
Neetik Mukherjee, Amlan K. Roy
Fisher information () is investigated in a confined harmonic oscillator (CHO) enclosed in a spherical enclosure, in conjugate and spaces. A comparative study between CHO…
