Two-pulse atomic coherent control

Two-pulse atomic coherent control (2PACC) spectroscopy is presented. The idea is demonstrated by simulating a source consisting of a two-pulse atom laser impinging on a surface covered with a co-adsorbed atom. The controlled outcome is an Eley–Rideal chemical reaction where the controls are the time delay and relative phase between the two-pulses. The two atom laser pulses interfere with each other as well as interact with the surface leading to a reaction with a co-adsorbed atom on the surface. The new-formed molecule desorbs and the flux of the desorption has been computed showing the predicted 2PACC signal.
