Half and quarter metals in rhombohedral trilayer graphene
Haoxin Zhou, Tian Xie, Areg Ghazaryan +8
Ferromagnetism is most common in transition metal compounds but may also arise in low-density two-dimensional electron systems, with signatures observed in silicon, III-V semicondu…
Long-range nontopological edge currents in charge-neutral graphene
Amit Aharon-Steinberg, Arthur Marguerite, David J. Perello +6
Van der Waals heterostructures display a rich variety of unique electronic properties. To identify novel transport mechanisms, nonlocal measurements have been widely used, wherein…
Chirality induced Giant Unidirectional Magnetoresistance in Twisted Bilayer Graphene
Yizhou Liu, Tobias Holder, Binghai Yan
Twisted bilayer graphene (TBG) exhibits fascinating correlation-driven phenomena like the superconductivity and Mott insulating state, with flat bands and a chiral lattice structur…
Nonvanishing sub-gap photocurrent as a probe of lifetime effects
Daniel Kaplan, Tobias Holder, Binghai Yan
For semiconductors and insulators, it is commonly believed that in-gap transitions into non-localized states are smoothly suppressed in the clean limit, i.e. at zero temperature th…
Consequences of Time-reversal-symmetry Breaking in the Light-Matter Interaction: Berry Curvature, Quantum Metric and Diabatic Motion
Tobias Holder, Daniel Kaplan, Binghai Yan
Nonlinear optical response is well studied in the context of semiconductors and has gained a renaissance in studies of topological materials in the recent decade. So far it mainly…
Visualizing Poiseuille flow of hydrodynamic electrons
Joseph A. Sulpizio, Lior Ella, Asaf Rozen +12
Hydrodynamics is a general description for the flow of a fluid, and is expected to hold even for fundamental particles such as electrons when inter-particle interactions dominate.…
