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…
Information-entropic measures for non-zero l states of confined hydrogen-like ions
Neetik Mukherjee, Amlan K. Roy
Relative Fisher information (IR), which is a measure of correlative fluctuation between two probability densities, has been pursued for a number of quantum systems, such as, 1D qua…
Relative Fisher information in some central potentials
Neetik Mukherjee, Amlan K. Roy
Relative Fisher information (IR), which is a measure of correlative fluctuation between two probability densities, has been pursued for a number of quantum systems, such as, 1D qua…
Quantum mechanical virial-like theorem for confined quantum systems
Neetik Mukherjee, Amlan K. Roy
Confinement of atoms inside impenetrable (hard) and penetrable (soft) cavities has been studied for nearly eight decades. However, a unified virial theorem for such systems has not…
