Query: Ab-initio Mapping of Projected Local Density of States in Arbitrary
  Nanostructures: Application to Photonic Crystal Slabs and Cavities   Based upon projected local density of states (PLDOS) for photons, we develop
a local coupling theory to simultaneously treat the weak and strong interaction
between a quantum emitter and photons in arbitrary nanostructures. The PLDOS is
mapped by an extremely flexible and efficient method. The recent experiment
observation for the photonic crystal slabs is very well interpreted by our
ab-initio PLDOS. More importantly, a bridge linking the PLDOS and cavity
quantum electrodynamics is for the first time established to settle quality
factor, g factor and vacuum Rabi splitting. Our work greatly enriches the
knowledge about the interaction between light and matter in nanostructures.
