Hyperradiance by a stream of phase-correlated atomic dipole pairs traversing a high-Q cavity

Abstract Hyperradiance in which radiation rate exceeds that of superradiance has been theoretically investigated in various coherently-coupled emitter-field systems. In most cases, either proposed setups were experimentally challenging or the mean photon number in a cavity was limited. In this paper...
