    <title language="eng">Chiral Nanophotonics: Theory and Simulation</title>
    <abstract language="eng">The interaction of light and chiral matter is subject of recent research both in fundamental science and applications.&#13;
Among these are the helicity of electromagnetic fields described with the optical chirality density and emitters sensitive to&#13;
circular polarization employed in quantum communications.&#13;
In the weak coupling regime of chiral emitters, we analyze the conversion of chirality which can be regarded as an analogue&#13;
to absorption of energy describing the change of circular polarization of the incident field. This enables the tailoring of&#13;
chiral near-fields close to metamaterials, e.g. composed of gold helices, and gives insights into extinction measurements&#13;
such as circular dichroism.&#13;
We show relation of the weak and strong coupling regime. The latter can be modelled with cross electric-magnetic polarizabilities or&#13;
with effective chiral materials, i.e. bi-anisotropic media. Accordingly, we motivate the necessity for rigorous numerical&#13;
simulations to accurately describe chiral light-matter interaction.</abstract>
