Title:Revival and Collapse of the Vibrational State Wave Packet for Diatomic Molecule in an Anharmonic Potential
Author Name:Maninder Kaur Boparai, Mahmood Mian and Manpreet Kaur
Synopsis:

This paper presents the time evolution of a quantum wave packet bound in the Morse potential. The quantum wave packet is the superposition of vibrational energy levels of a diatomic molecule in an anharmonic potential. The probability density function, auto-correlation function, and various time scales have been used to explore the revival pattern of this wave packet. The dynamics of the wave packet with respect to time shows a series of collapses and the subsequent revivals. The results are presented for CO molecule.
