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…
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…
Signatures of Chiral Superconductivity in Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Zach Hadjri +20
Chiral superconductors are unconventional superconducting states that break time reversal symmetry spontaneously and typically feature Cooper pairing at non-zero angular momentum.…
Impact of Spin-Orbit Coupling on Superconductivity in Rhombohedral Graphene
Jixiang Yang, Xiaoyan Shi, Shenyong Ye +10
Spin-orbit coupling (SOC) has played an important role in many topological and correlated electron materials. In graphene-based systems, SOC induced by transition metal dichalcogen…
