Plasmon-polaron of the topological metallic surface states
We report a plasmon-polaron mode of a two-dimensional electron gas occupying surface states of a three-dimensional topological crystal. This low-frequency, acoustic plasmon mode splits off from the conventional spin-plasmon mode as a result of strong interactions of the surface electrons with bulk p...
