Chiral and chemical oscillations in a simple dimerization model

Abstract

We consider the APED model (activation-polymerization–epimerization-depolymerization) for describing the emergence of chiral solutions within a non-catalytic framework for chiral polymerization. The minimal APED model for dimerization can lead to the spontaneous appearance of chiral oscillations and we describe in detail the nature of these oscillations in the enantiomeric excess, which are the consequence of oscillations of the concentrations of the associated chemical species.
