Coherent Control and chaos in the multiphoton dissociation of diatomic molecules

Emanuel Lima
In this work, we compare the quantum and classical dissociation dynamics of nonrotating diatomic
molecules under infrared laser pulses. The electric field is given by Gaussian pulses of commensurate frequencies. We investigate the role of amplitude, carrier
frequency and relative phase on the dissociation probability. We also vary the initial vibrational
state, with the objective of find reasonable quantum-classical correspondence. Through direct
comparison of the quantum and classical theories, we investigate the role of relative phase and
synchronization of multiple pulses on the dynamics. Special attention is paid to the analogies
between coherent control and classical chaos.
