Dissociation and ionization of small molecules steered by external noise

TL;DR

This paper demonstrates that external noise can selectively control dissociation and ionization in molecules, specifically in the hydrogen molecular ion, by tuning stochastic forces to achieve dissociation without ionization.

Contribution

It introduces a quantum mechanical approach beyond the Born-Oppenheimer approximation to manipulate molecular processes using external stochastic forces.

Findings

Up to 30% dissociation without ionization achieved.

External noise can be tuned to control molecular dissociation.

Quantum effects are considered beyond the Born-Oppenheimer approximation.

Abstract

We show that ionization and dissociation can be influenced separately in a molecule with appropriate external noise. Specifically we investigate the hydrogen molecular ion under a stochastic force quantum mechanically beyond the Born-Oppenheimer approximation. We find that up to 30% of dissociation without ionization can be achieved by suitably tuning the forcing parameters.
