Equivalence of the Kobrak–Rice photoselective adiabatic passage and the Brumer–Shapiro strong field methods for control of product formation in a reaction

Mark N. Kobrak, Stuart A. Rice

It is shown that the photoselective adiabatic passage approach to control of product formation in a chemical reaction proposed by Kobrak and Rice may be viewed as a high-field limit of the strong field Brumer–Shapiro scheme. It is further shown that the adiabatic passage representation provides new insight into the nature of control over chemical reactions in strong fields, and that it correctly predicts the results of physically realistic simulations of the sodium dimer.

Formation of slow molecules in chemical reactions in crossed molecular beams

We demonstrate that chemical reactions in collisions of molecular beams can generally produce low-velocity molecules in the laboratory-fixed frame. Our analysis shows that collisions of beams may simultaneously yield slow reactant molecules and slow products. The reaction products are formed in selected rovibrational states and scattered in a specific direction, which can be controlled by tuning the kinetic energies of the incident beams and the angle between the beams. Our calculations indicate that chemical reactions of polar alkali-metal dimers are barrierless and we suggest that chemical reactions involving alkali-metal dimers may be particularly suitable for producing slow molecules in crossed beams.We demonstrate that chemical reactions in collisions of molecular beams can generally produce low-velocity molecules in the laboratory-fixed frame.

Coherent control and geometric phase

Xuan Li

We present the ability to coherently control triatomic chemical reactions with pulsed-laser techniques. We show that one can control the final state probability distribution of triatomic chemical reactions with nearly 100% selectivity. We develop the population transfer by adiabatic passage theory to coherently control the chemical reaction with the ability of choosing the translational energies of the final reaction products. We also show a new way to achieve the creation of both homonuclear and heteronuclear diatomic molecules at an ultracold temperature using laser catalysis.We present the ability to coherently control triatomic chemical reactions with pulsed-laser techniques.
