A Unifying Framework for Fractional Chern Insulator Stabilization
Peleg Emanuel, Anna Keselman, Yuval Oreg
We present a theory of fractional Chern insulator stabilization against charge-ordered states. We argue that the phase competition is captured by an effective interaction range, wh…

Visualizing isospin magnetic texture and intervalley exchange interaction in rhombohedral tetralayer graphene
Nadav Auerbach, Surajit Dutta, Matan Uzan +13
The tunable band structure and nontrivial topology of multilayer rhombohedral graphene lead to a variety of correlated electronic states with isospin orders-meaning ordered states…

Band Renormalization, Quarter Metals, and Chiral Superconductivity in Rhombohedral Tetralayer Graphene
Guillermo Parra-Martinez, Alejandro Jimeno-Pozo, Vo Tien Phong +7
Recently, exotic superconductivity emerging from a spin-and-valley-polarized metallic phase has been discovered in rhombohedral tetralayer graphene. To explain this observation, we…
