Multipolar Light-Matter Coupling in Nanostructures: From Ultrafast Radiative Decay to Forbidden Molecular Transitions

We review optical responses in the nano-to-bulk crossover, where bulk translational symmetry no longer applies and the long-wavelength approximation (LWA) often fails. In this regime, the response must be treated nonlocal, and a self-consistent solution of Maxwell’s equations and...
