Rotating Morse wave packet dynamics of diatomic molecule
Utpal Roy, Suranjana Ghosh
We investigate the dynamics of a rotating Morse wave packet, appropriate for a ro-vibrating diatomic molecule. The coupling between vibrational and rotational degrees of freedom is…

Sub-Planck scale structures in the P{ö}schl-Teller potential and their sensitivity to perturbations
Utpal Roy, Suranjana Ghosh, P. K. Panigrahi +1
We find the existence of sub-Planck scale structures in the P{ö}schl-Teller potential, which is an exactly solvable potential with both symmetric and asymmetric features. We analyz…

Sub-Planck scale structures in a vibrating molecule in the presence of decoherence
Suranjana Ghosh, Utpal Roy, Claudiu Genes +1
We study the effect of decoherence on the sub-Planck scale structures of the vibrational wave packet of a molecule. The time evolution of these wave packets is investigated under t…
