Lindbladian Phase Geometry and Hall Transport in Open Bloch Systems
Zhihao Jiang, Longjun Xiang, Jian Wang
Quantum geometry underlies a wide range of transport phenomena in Bloch systems. How quantum-geometric transport is modified when Bloch electrons are coupled to an environment, how…
Integrating Magnons for Quantum Information
Zhihao Jiang, Jinho Lim, Yi Li +7
Magnons, the quanta of collective spin excitations in magnetically ordered materials, have distinct properties that make them uniquely appealing for quantum information application…
Programming moiré patterns in 2D materials by bending
Mäelle Kapfer, Bjarke S. Jessen, Megan E. Eisele +20
Moiré superlattices in twisted two-dimensional materials have generated tremendous excitement as a platform for achieving quantum properties on demand. However, the moiré pattern i…
Plasmons in Z2 Topological Insulators
Yuling Guan, Stephan Haas, Henning Schlomer +1
We study plasmonic excitations in the Kane-Mele model, a two-dimensional Z2 topological insulator on the honeycomb lattice, using the random phase approximation (RPA). In the topol…
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.…
