Chiral plasmons with twisted atomic bilayers
Xiao Lin, Zifei Liu, Tobias Stauber +5
Van der Waals heterostructures of atomically thin layers with rotational misalignments, such as twisted bilayer graphene, feature interesting structural moiré superlattices. Due to…
Change of chirality at magic angles of twisted bilayer graphene
T. Stauber, J. González, G. Gómez-Santos
We derive a simple formula for the real-space chirality of twisted bilayer graphene that can be related to the cross-product of its sheet currents. This quantity shows well-defined…
Non-local quantum effects in plasmons of graphene superlattices
Luis Brey, T. Stauber, L. Martín-Moreno +1
By using a non-local, quantum mechanical response function we study graphene plasmons in a one-dimensional superlattice (SL) potential . The SL introduces a quantum…
Emergent magnetic texture in driven twisted bilayer graphene
D. A. Bahamon, G. Gómez-Santos, T. Stauber
The transport properties of a twisted bilayer graphene barrier are investigated for various twist angles. Remarkably, for small twist angles around the magic angle $θ_m \sim 1.05^{…
Unidirectional plasmonic edge modes on general two-dimensional materials
T. Stauber, A. Nemilentsau, T. Low +1
We investigate the field and spin-momentum coupling of edge plasmons hosted by general two-dimensional materials and identify sweet spots depending on the polarisation plane, ellip…
Linear response of twisted bilayer graphene: continuum vs. tight-binding models
T. Stauber, T. Low, G. Gómez-Santos
We present a linear response calculation for twisted bilayer graphene. The calculation is performed for both the continuum and tight-binding models, with the aim of assessing the v…
