Quantum Control of Atom-Ion Charge Exchange via Light-Induced Conical Intersections.

ABSTRACT: Conical intersections are crossing points or lines between two or more adiabatic electronic potential energy surfaces in the multidimensional coordinate space of colliding atoms and molecules. Conical intersections and corresponding nonadiabatic coupling can greatly affect molecular dynamics and chemical properties. In this paper, we predict significant or measurable nonadiabatic effects in an ultracold atom-ion charge-exchange reaction in the presence of laser-induced conical intersections (LICIs). We investigate the fundamental physics of these LICIs on molecular reactivity under unique conditions: those of relatively low laser intensity of 10⁸ W/cm² and ultracold temperatures below 1 mK. We predict irregular interference effects in the charge-exchange rate coeffici
