Energy landscape that governs the chemical reaction of two molecules after the system absorbs one single photon. At the first reaction step t0 the system consists of five molecules strongly interacting with the electromagnetic vacuum. At the second reaction step t1 the system has evolved and one molecule has isomerized. In the strong coupling regime this process continues with more steps in which one molecule isomerizes after another.
