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…
Ro-vibrational energy analysis of Manning-Rosen and Pöschl-Teller potentials with a new improved approximation in the centrifugal term
Debraj Nath, Amlan K. Roy
Two physically important potentials (Manning-Rosen and Pöschl-Teller) are considered for the ro-vibrational energy in diatomic molecules. An improved new approximation is invoked f…
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…
Analytical solution of dimensional Schrödinger equation for Eckart potential with a new improved approximation in centrifugal term
Debraj Nath, Amlan K. Roy
Analytical solutions are presented for eigenvalues, eigenfunctions of {\color{red} D-dimensional Schrodinger equation having Eckart potential} within Nikiforov-Uvarov method. This…
Shell-confined atom and plasma: incidental degeneracy, metallic character and information entropy
Neetik Mukherjee, Amlan K. Roy
Shell confined atom can serve as a generalized model to explain both \emph{free} and \emph{confined} condition. In this scenario, an atom is trapped inside two concentric spheres o…
