Constructive Quantum Interference in a Photo-Chemical Reaction of BEC

ORAL

Abstract

Interferences emerge when multiple pathways coexists together leading towards the same result. A recent study by Yong and coworkers (PRL 121, 073202, 2018) showed that in a photo-association reaction of Raman dressed spin-orbit coupled 87Rb Bose-Einstein Condensate when the reactant spin state is prepared in a coherent superposition of multiple bare spin states it leads to destructive interference between reaction pathways. Here we report a theoretical study suggesting the existence of a reaction scheme which leads to constructive quantum interference. This can be achieved by changing the reactive scattering channel in the reaction and our results show that interferences can be used as a resource for the coherent control of a Photo-chemical reaction.
