Competing Chern states revealed by quasiparticle charging in moiré rhombohedral graphene
Hongyuan Li, Zuhan Geng, Junseok Seo +13
Moiré materials realize a versatile platform for exploring the physics of fractional Chern insulators (FCIs). The recently observed evolution from FCIs to an extended quantum anom…
Imaging Interacting Two-Dimensional Anisotropic Electrons
Ziyu Xiang, Jianghan Xiao, Hongyuan Li +9
We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with…
Magnetic-field-induced superconductivity in hexalayer rhombohedral graphene
Jinghao Deng, Jiabin Xie, Hongyuan Li +5
In conventional superconductors, superconductivity is generally suppressed by external magnetic fields due to spin-singlet pairing. Here, we report signatures of in-plane-magnetic-…
Superconductivity and Ferroelectric Orbital Magnetism in Semimetallic Rhombohedral Hexalayer Graphene
Jinghao Deng, Jiabin Xie, Hongyuan Li +5
Rhombohedral multilayer graphene has emerged as a promising platform for exploring correlated and topological quantum phases, enabled by its Berry-curvature-bearing flat bands. Whi…
Imaging Tunable Luttinger Liquid Systems in van der Waals Heterostructures
Hongyuan Li, Ziyu Xiang, Tianle Wang +16
One-dimensional (1D) interacting electrons are often described as a Luttinger liquid1-4 having properties that are intrinsically different from Fermi liquids in higher dimensions5,…
