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 the Meissner effect and local superfluid stiffness in a graphene superconductor
Ruoxi Zhang, Benjamin A. Foutty, Owen Sheekey +15
We report the observation of the Meissner effect in a rhombohedral graphene superconductor, realized via direct imaging of the static fringe magnetic field. In our few-micron sampl…
Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
Ludwig Holleis, Tian Xie, Siyuan Xu +9
Magnetism typically arises from the effect of exchange interactions on highly localized fermionic wave functions in f- and d-atomic orbitals. In rhombohedral multilayer graphene (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…
Optical Imaging of Flavor Order in Flat Band Graphene
Tian Xie, Tobias M. Wolf, Siyuan Xu +15
Spin and valley flavor polarization plays a central role in the many-body physics of flat band graphene, with fermi surface reconstructions often accompanied by quantized anomalous…
