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. WebPolaritons Transverse optical phonons will couple to photons with the same and k. photon dispersion avoided crossing Light Bragg reflects off the sound wave; sound Bragg reflects off the light wave.
WebJun 17, 2024 · An external field resonant with the lower polariton (LP) drives the hybrid cavity and excites two-LP states which can be tuned to be near resonant with the anharmonically shifted doubly excited molecular states forming the totally symmetric 2 s state. This polariton-mediated absorption channel allows enhancement of several orders … WebWe present a fully microscopic approach to the transition rate of two exciton-photon polaritons. The non-trivial consequences of the polariton composite nature -- here treated exactly through a development of our composite-exciton many-body theory -- lead to results noticeably different from the ones of the conventional approaches in which polaritons are …
WebApr 19, 2024 · The polariton lasing is confirmed with large Rabi splitting energies in 1D exciton polariton dispersion relations. The double threshold behavior well below and above the Mott density, observed in the quantum heterostructure nanocavities, evidences the transition from polariton to photon lasing regimes. 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 ...
