Plasmonic Waveguides from Coulomb-Engineered Two-Dimensional Metals
Zhihao Jiang, Stephan Haas, Malte Rösner
Coulomb interactions play an essential role in atomically-thin materials. On one hand, they are strong and long-ranged in layered systems due to the lack of environmental screening…
Control of Plasmons in Topological Insulators via Local Perturbations
Yuling Guan, Zhihao Jiang, Stephan Haas
We use a fully quantum mechanical approach to demonstrate control of plasmonic excitations in prototype models of topological insulators by molecule-scale perturbations. Strongly l…
Control of Plasmons in Doped Topological Insulators via Basis Atoms
Zhihao Jiang, Henning Schlömer, Stephan Haas
Collective excitations in topologically non-trivial systems have attracted considerable attention in recent years. Here we study plasmons in the Su-Schrieffer-Heeger model whose lo…
Plasmons in Two-Dimensional Topological Insulators
Henning Schlömer, Zhihao Jiang, Stephan Haas
We analyze collective excitations in models of two-dimensional topological insulators using the random phase approximation. In a two-dimensional extension of the Su-Schrieffer-Heeg…
Localized Plasmons in Topological Insulators
Zhihao Jiang, Malte Rösner, Roelof E. Groenewald +1
We investigate in a fully quantum-mechanical manner how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions.…
