Design of Monolithic Microcavities for Enhancing Organic Quantum Emitters

Abstract Single organic molecules are a well-established platform for high-quality single-photon generation: they can emit lifetime-limited photons with high purity and indistinguishability. However, their emission is accompanied by a pronounced red-shifted phonon sideband and hi...

Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm

Abstract The transition matrix (T-matrix) is a complete description of an object’s linear scattering response. As such, it has found wide adoption for the theoretical and computational description of multiple-scattering phenomena. In its original form, the T-matrix describes the...
