WebSurface phonon-polaritons (SPhPs) are evanescent electromagnetic waves that can propagate distances orders of magnitude longer than the typical mean free paths of phonons and electrons. Therefore, they are expected to be powerful heat carriers capable of significantly enhancing the in-plane thermal conductance of polar nanostructures. In this … WebMar 4, 2024 · There have been several reports on the exciton–photon coupling in GaN-based microcavities (double DBR planar cavity), and always show the angle-depended PL …
WebFeb 20, 2024 · This polariton propagates through the gas like a slow-moving photon with non-zero mass. When it reaches the opposite edge of the gas, the polariton is converted back to light. The presence of a Rydberg polariton prevents nearby photons from creating their own excitations – a phenomenon called Rydberg blockade. WebDec 12, 2003 · The photon component of a polariton has a fixed decay rate (normally on the order of 0.1 THz) out of the cavity. The emission of a photon preserves the polariton …

This polariton-mediated absorption channel allows enhancement of several orders …
WebJul 1, 2015 · Taken separately, the underlying photons and excitons are topologically trivial. Combined appropriately, however, they give rise to nontrivial polaritonic bands with chiral edge modes allowing for unidirectional polariton propagation. The main ingredient in our construction is an exciton-photon coupling with a phase that winds in momentum space.
