Orbital-Free Density Functional Theory for Periodic Solids: Construction of the Pauli Potential
Sangita Majumdar, Zekun Shi, Giovanni Vignale
The practical success of density functional theory (DFT) is largely credited to the Kohn-Sham approach, which enables the exact calculation of the non-interacting electron kinetic…
Information entropy in excited states in confined quantum systems
Sangita Majumdar, Neetik Mukherjee, Amlan K. Roy
The present contribution constitutes a brief account of information theoretical analysis in several representative model as well as real quantum mechanical systems. There has been…
Confined H ion within a density functional framework
Sangita Majumdar, Neetik Mukherjee, Amlan K. Roy
Ground and excited states of a confined negative Hydrogen ion has been pursued under Kohn-Sham density functional approach by invoking a physically motivated work-function-based ex…
Density functional study of atoms spatially confined inside a hard sphere
Sangita Majumdar, Amlan K. Roy
An atom placed inside a cavity of finite dimension offers many interesting features, and thus has been a topic of great current activity. This work proposes a density functional ap…
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…
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…
Various complexity measures in confined hydrogen atom
Sangita Majumdar, Neetik Mukherjee, Amlan K. Roy
Several well-known statistical measures similar to \emph{LMC} and \emph{Fisher-Shannon} complexity have been computed for confined hydrogen atom in both position () and momentum…
Fisher information in confined hydrogen-like ions
Neetik Mukherjee, Sangita Majumdar, Amlan K. Roy
Fisher information (I) is investigated for confined hydrogen atom (CHA)-like systems in conjugate and spaces. A comparative study between CHA and free H atom (with respect…
