Research paperTheoreticalComputed RamanQuantum Band Structure and Topology in One Dimensional Modulated Plasmonic CrystalLuis Brey, H.A. FertigarXiv·2024·10.1103/physrevb.111.045430·arXiv:2410.11626AbstractWe study topology of plasmons in a two-dimensional metal with unidirectional periodicity, focusing on graphene with a periodic modulation of the Fermi energy. Using a quantum Hamiltonian for confined plasmon modes, we compute plasmon band structures and wavefunctions for Kronig-Penney-like and SSH-like plasmonic crystals, analyze Zak phases and topological invariants, and show that non-trivial gaps host interface-localized in-gap states.Read more
