Non-linear optics at twist interfaces in h-BN/SiC heterostructures
Abhijit Biswas, Rui Xu, Gustavo A. Alvarez +24
Understanding the emergent electronic structure in twisted atomically thin layers has led to the exciting field of twistronics. However, practical applications of such systems are…
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…
Ultrafast Spin Dynamics and Photoinduced Insulator-to-Metal Transition in -
Jin Zhang, Nicolas Tancogne-Dejean, Lede Xian +4
Laser-induced ultrafast demagnetization is a phenomenon of utmost interest and attracts significant attention because it enables potential applications in ultrafast optoelectronics…
Probing phonon dynamics with multi-dimensional high harmonic carrier envelope phase spectroscopy
Ofer Neufeld, Jin Zhang, Umberto De Giovannini +2
We explore pump-probe high harmonic generation (HHG) from monolayer hexagonal-Boron-Nitride, where a terahertz pump excites coherent optical phonons that are subsequently probed by…
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…
