Author(s): Adrien Reingruber, Maksim Ulybyshev, and Kitinan Pongsangangan Transport properties of strongly correlated materials have contributions from quasiparticle excitations such as electrons and holes as well as emerging collective excitations such as plasmonic soundlike modes which are sustained by interactions. It was previously shown by Pongsangangan et al. [ Phys.… [Phys. Rev. B 114, 165114] Published Thu Sep 10, 2026
