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…
Moiré heterostructures as a condensed matter quantum simulator
Dante M. Kennes, Martin Claassen, Lede Xian +7
Twisted van der Waals heterostructures have latterly received prominent attention for their many remarkable experimental properties, and the promise that they hold for realising el…
Optical Manipulation of Domains in Chiral Topological Superconductors
Tao Yu, Martin Claassen, Dante M. Kennes +1
Optical control of chirality in chiral superconductors bears potential for future topological quantum computing applications. When a chiral domain is written and erased by a laser…
Light-induced topological magnons in two-dimensional van der Waals magnets
Emil Viñas Boström, Martin Claassen, James W. McIver +3
Driving a two-dimensional Mott insulator with circularly polarized light breaks time-reversal and inversion symmetry, which induces an optically-tunable synthetic scalar spin chira…
Observing photo-induced chiral edge states of graphene nanoribbons in pump-probe spectroscopies
Yuan Chen, Yao Wang, Martin Claassen +2
Photo-induced edge states in low dimensional materials have attracted considerable attention due to the tunability of topological properties and dispersion. Specifically, graphene…
Realization of Nearly Dispersionless Bands with Strong Orbital Anisotropy from Destructive Interference in Twisted Bilayer MoS2
Lede Xian, Martin Claassen, Dominik Kiese +4
Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructur…
