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…
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…
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…
Propagating Collective Spin-valley Modes in Twisted WSe2
Richen Xiong, Yi Guo, Chenxin Qin +15
The emergence of neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe experimentally. In two-dimensional flatband systems, charge r…
Superconductivity and spin canting in spin-orbit proximitized rhombohedral trilayer graphene
Caitlin L. Patterson, Owen I. Sheekey, Trevor B. Arp +15
Graphene and transition metal dichalcogenide flat-band systems show similar phase diagrams, replete with magnetic and superconducting phases. An abiding question has been whether m…
