Abstract
The formation and dynamics of excitations in an atomic or molecular nano chain of a helical shape is studied. The dipole-dipole interaction of the circular polarizations of optical transitions of neighboring molecules is taken into account. The derived Bloch equations are solved in a continuum approximation using the Frenet - Serret coordinate system. Solutions that describe the formation of stable localized structures, solitons, due to the curvature of the chain, which can have a critical influence on the luminescent properties of the chiral medium.
