Photon dispersion relation

WebThe general dispersion relation can be significantly simplified under the assumption of large refractive indices of the modes. ... They are half-light (photon) and half-matter (excitons), and are formed when excitons are created in a high-finesse optical cavity. Polaritons are bosons with an integral spin but very small mass. WebOct 1, 2013 · Therefore, the modified photon velocity turns out to be (16) u = c (1 + 2 α E c − g 00). Second, it is evident that there is a velocity dispersion and that the photon velocities are energy-dependent. Moreover, since photon velocity u can take larger values than c, superluminal photon propagation is allowed due to quantum gravity corrections ...
