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…
Lithography defined semiconductor moires with anomalous in-gap quantum Hall states
Wei Pan, D. Bruce Burckel, Catalin D. Spataru +16
Quantum materials and phenomena have attracted great interest for their potential applications in next-generation microelectronics and quantum-information technologies. In one espe…
Isoperimetric Inequalities in Quantum Geometry
Praveen Pai, Fan Zhang
We reveal strong and weak inequalities relating two fundamental macroscopic quantum geometric quantities, the quantum distance and Berry phase, for closed paths in the Hilbert spac…
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…
Self-consistent theory for the fractional quantum anomalous Hall effect in rhombohedral pentalayer graphene
Ke Huang, Xiao Li, Sankar Das Sarma +1
The fractional quantum anomalous Hall (FQAH) effect in rhombohedral pentalayer graphene (PLG) has attracted significant attention due to its potential for observing exotic quantum…
