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. WebThe component of the scattering vector parallel to the surface results in the formation of a surface plasmon polariton. For a photon to excite an SPP, both must have the same frequency and momentum. However, for a given frequency, a free-space photon has less momentum than an SPP because the two have different dispersion relations (see below ...
