Wigner Distribution and Boltzmann-Shannon Entropy for a Diatomic Molecule under Polarized Electric Field Interaction II: A Recent Study

September 7, 2021 Physical Science 0

We look at the classical chaos that appears in diatomic molecules like BeO, CO, and CN when they interact with a circularly polarised electric field, as well as the Wigner distribution function and the Boltzmann-Shannon entropy in Quantum Mechanics. When the classical system becomes chaotic, we observed a motion out of the centre of the quantum phase space defined by the Wigner function, as well as a jumping behaviour of the average Boltzmann-Shannon entropy with respect to the electric field strength, indicating a sudden increase in the disorder (or sudden loss of information) in the quantum system. The study was done to be able to take it further with the parameter Wc since a much larger number of states must be examined, but the BS entropy is expected to rise further as more states are involved in quantum dynamics.
