A time-based Chern number in periodically-driven systems in the adiabatic limit
I-Te Lu, Dongbin Shin, Umberto De Giovannini +4
To define the topology of driven systems, recent works have proposed synthetic dimensions as a way to uncover the underlying parameter space of topological invariants. Using time a…
Identification of the Mott insulating CDW state in 1T-TaS
Dongbin Shin, Nicolas Tancogne-Dejean, Jin Zhang +3
We investigate the low-temperature charge-density-wave (CDW) state of bulk TaS with a fully self-consistent DFT+U approach, over which the controversy has remained unresolved r…
Engineering Three Dimensional Moiré Flat Bands
Lede Xian, Ammon Fischer, Martin Claassen +3
We demonstrate that the concept of moiré flat bands can be generalized to achieve electronic band engineering in all three spatial dimensions. For many two dimensional van der Waal…
Graphene/-RuCl: An Emergent 2D Plasmonic Interface
Daniel J. Rizzo, Bjarke S. Jessen, Zhiyuan Sun +16
Work function-mediated charge transfer in graphene/-RuCl heterostructures has been proposed as a strategy for generating highly-doped 2D interfaces. In this geometry, graphe…
