Interaction of Rydberg excitons in cuprous oxide with phonons and photons: optical linewidth and polariton effect
We demonstrate that the optical linewidth of Rydberg excitons in Cu _2 O can be completely explained by scattering with acoustical and optical phonons, whereby the dominant contributions stems from the non-polar optical ${{\rm{\Gamma }}}_{3}^{-}$ and ${{\rm{\Gamma }}}_{5}^{-}$ modes. The consequence...

| description | We demonstrate that the optical linewidth of Rydberg excitons in Cu _2 O can be completely explained by scattering with acoustical and optical phonons, whereby the dominant contributions stems from the non-polar optical ${{\rm{\Gamma }}}_{3}^{-}$ and ${{\rm{\Gamma }}}_{5}^{-}$ modes. The consequences for the observation of polariton effects are discussed. We find that an anti-crossing of photon and exciton dispersions exists only for states with main quantum numbers n > 28, so polariton effects do not play any role in the experiments reported up to now. |
