Spectral Singularities and Whispering Gallery Modes of a Cylindrical Gain Medium
, 2013 Complex scattering potentials can admit scattering states that behave exactly like a zero-width resonance. Their energy is what mathematicians call a spectral singularity. This phenomenon admits optical realizations in the form of lasing at the threshold

Nuclear Rayleigh and whispering gallery waves excited in heavy ion collisions
Physics Letters B, 1980 Abstract The gross structure oscillations recently observed in heavy-ion elastic or inelastic scattering and fusion cross sections are here analyzed in terms of nuclear surface (creep) wave resonances. Their dispersion curves characterize these waves as being of Rayleigh or of Whispering-Gallery type.

Complete linear optical isolation at the microscale with ultralow loss
Scientific Reports, 2017 Low-loss optical isolators and circulators are critical nonreciprocal components for signal routing and protection, but their chip-scale integration is not yet practical using standard photonics foundry processes. The significant challenges that confront
