Multi-Knob Switchable Chiral Superconductivity Quartet in Rhombohedral Graphene
Zhenqi Hua, Shenyong Ye, Phatthanon Pattanakanvijit +17
Chiral superconductors break orbital time-reversal symmetry and may host topological quasiparticles with non-Abelian statistics. In rhombohedral graphene, superconductivity develop…
1/3 Fractional and Gapless Integer Quantum Anomalous Hall States in Rhombohedral Graphene
Jackson P. Butler, Tonghang Han, Andrew DiFabbio +6
The fractional quantum anomalous Hall (FQAH) effect occurs in moiré superlattices in both twisted bilayer MoTe and rhombohedral -layer graphene aligned to hexagonal boron n…
Evidence of Metallic Wigner Crystal in Rhombohedral Graphene
Tonghang Han, Jackson P. Butler, Shenyong Ye +15
When the Coulomb interaction dominates over kinetic energy, electrons can crystallize into a Wigner crystal (WC). This paradigmatic correlated electronic phase has been realized in…
Magnetic Field-Enhanced Graphene Superconductivity with Record Pauli-Limit Violation
Jixiang Yang, Omid Sharifi Sedeh, Chiho Yoon +22
Spin-polarized superconductors offer a rare platform for studying electronic correlations, but few candidate systems have been experimentally confirmed to date. Here, we report the…
Family of Unconventional Superconductivities in Crystalline Graphene
Junseok Seo, Armel A. Cotten, Mingchi Xu +17
Unconventional superconductors exhibit multiple broken symmetries and exceed the range of the Bardeen-Cooper-Schrieffer (BCS) theory. For instance, time-reversal symmetry can be br…
