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…
Lower bound of the expressibility of ansatzes for Variational Quantum Algorithms
Tamojit Ghosh, Arijit Mandal, Shreya Banerjee +2
The expressibility of an ansatz used in a variational quantum algorithm is defined as the uniformity with which it can explore the space of unitary matrices, i.e., its covering num…
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…
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…
Information entropy as a measure of tunneling and quantum confinement in a symmetric double-well potential
Neetik Mukherjee, Arunesh Roy, Amlan K. Roy
Information entropic measures such as Fisher information, Shannon entropy, Onicescu energy and Onicescu Shannon entropy of a symmetric double-well potential are calculated in both…
