Observation of metastable chiral domain walls in a topological magnet
Richen Xiong, Chenxin Qin, Zhaoyu Han +17
The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…
Cryogenic shock exfoliation for ultrahigh mobility rhombohedral graphite nanoelectronics
Ludwig Holleis, Youngjoon Choi, Canxun Zhang +16
Rhombohedral multilayer graphene (RMG) offers a highly tunable platform for correlated electron physics, featuring field-effect control of magnetic, superconducting, and topologica…
Electrostatically stabilized surface flat bands in rhombohedral graphite at zero displacement field
KryÅ¡tof KoláÅ, Andrea F. Young, Cyprian Lewandowski
Rhombohedral (ABC-stacked) multilayer graphene hosts interaction-driven phases enabled by surface flat bands at large displacement fields. In thick flakes, however, strong screenin…
Visualizing orbital magnetism in electron doped rhombohedral multilayer graphene
Owen I. Sheekey, Trevor B. Arp, Benjamin A. Foutty +24
Electron doped rhombohedral multilayer graphene at high displacement field features an exceptionally flat band minimum with near-ideal quantum geometry. Experiments in this regime…
Imaging flat band electron hydrodynamics in biased bilayer graphene
Canxun Zhang, Evgeny Redekop, Hari Stoyanov +12
Hydrodynamic electron transport arises when carrier kinetics are dominated by interelectron collisions rather than the relaxation of momentum out of the electron system. In recent…
Van Hove Singularity-Driven Topological Magnetism in Twisted MoTe2
Heonjoon Park, Julian Stewart, Xiao-Wei Zhang +15
Van Hove singularities (vHSs) strongly amplify electron interactions and can stabilize correlated phases in topological bands. Here we report signatures of topological magnetism in…
