Thermodynamic evidence for interaction-driven first-order topological quantum phase transitions
Surajit Dutta, Nadav Auerbach, Chiho Yoon +12
Topological quantum phase transitions in non interacting systems occur through continuous gap closing and reopening. In strongly interacting systems, however, competing ordered sta…
Majorana Crystal in Rhombohedral Graphene
Chiho Yoon, Fan Zhang
Recent experiments in rhombohedral graphene report an unusual superconducting phase emerging from a spin- and valley-polarized quarter-metal state. The prevailing interpretation 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…
Quarter Metal Superconductivity
Chiho Yoon, Tianyi Xu, Yafis Barlas +1
We investigate the recently discovered multiple superconducting states in rhombohedral graphene quarter metal. We demonstrate that one of these states features a single-spin, singl…
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…
