Multiple transitions induced by light intensity fluctuations in illuminated chemical systems

RESUMO
The influence of external noise on the steady-state properties of a chemical system with very simple kinetics was studied. We dealt with an isomerization reaction, in a closed system, coupled to a light absorption and radiationless deexcitation process involving only one of the isomers. The theoretical analysis established that external noise deeply modified the macroscopic properties of the system and even induced transition phenomena that are totally unexpected from the usual deterministic description.
