Importance of long-ranged electron-electron interactions for the magnetic phase diagram of twisted bilayer graphene
Lennart Klebl, Zachary A. H. Goodwin, Arash A. Mostofi +2
Electron-electron interactions are intrinsically long ranged, but many models of strongly interacting electrons only take short-ranged interactions into account. Here, we present 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…
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…
Universal moiré nematic phase in twisted graphitic systems
Carmen Rubio-Verdú, Simon Turkel, Larry Song +12
Graphene moiré superlattices display electronic flat bands. At integer fillings of these flat bands, energy gaps due to strong electron-electron interactions are generally observed…
Influence of spin and orbital fluctuations on Mott-Hubbard exciton dynamics in LaVO Thin Films
D. J. Lovinger, M. Brahlek, P. Kissin +4
Recent optical conductivity measurements reveal the presence of Hubbard excitons in certain Mott insulators. In light of these results, it is important to revisit the dynamics of t…
