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…
Probing Plasmonic Oscillations in 2D Moiré Nanocrystal Superlattices by Low-Loss EELS
Swarnendu Das, Shengsong Yang, Kevin N. Moser +5
Electron energy loss spectroscopy (EELS) has been established as a powerful analytical technique for investigating the oxidation state, band structure, and dielectric properties of…
Substrate matters: Coupled phonon modes of a spherical particle on a substrate probed with EELS
Ka Yin Lee, Elliot K. Beutler, Tifany Q. Crisolo +2
Using vibrational electron energy loss spectroscopy (vib-EELS) combined with numerical modeling, we investigate the physical mechanisms governing the phonon coupling between a sphe…
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…
Strongly coupled photonic molecules as doubly-coupled oscillators
Kevin C. Smith, Austin G. Nixon, David J. Masiello
In this work, we present a field-theoretic model of strongly coupled photonic molecules composed of interacting dielectric cavities in a closed, perfect-electric-conductor domain.…
