Unified light-matter metric of molecular and nanophotonic chirality
Kevin N. Moser, Marc R. Bourgeois, David J. Masiello
Signatures of a material object's broken inversion symmetry within its intrinsic excitations and associated optical fields have largely evaded characterization from a perspective t…

Conservation of Pseudoangular Momentum in the Radiative Emission and Optical Excitation of Valley-Polarized Surface Lattice Resonances
Siamak Khorasani, Marc R. Bourgeois, David J. Masiello
Surface lattice resonances (SLRs) are collective polaritonic excitations in nanoparticle arrays, with band-edge states enabling symmetry-based control of radiation including scatte…

Conservation of optical chirality in nanoscale light-matter interactions: A study of the Born-Kuhn model system
Kevin N. Moser, Marc R. Bourgeois, Elliot K. Beutler +1
Optical chirality density is a measure of the local handedness of electromagnetic fields. Like energy density, it may be absorbed or scattered through the interaction between light…
