From Fractionalization to Chiral Topological Superconductivity in a Flat Chern Band

Puntos clave

Chiral f-wave topological superconductivity arises from an interaction-induced metallic state, leading to Majorana edge modes.
Notable phenomena include the anomalous Hall effect observed in rhombohedral graphene.
Analysis within flat Chern bands indicates potential for new topological phases of matter including fractional Chern insulators.
This study may inspire further exploration of superconductivity and topological phenomena in advanced materials.

Resumen

We show that interacting electrons in a flat Chern band can form, in addition to fractional Chern insulators, a chiral f-wave topological superconductor that hosts neutral Majorana fermion edge modes. Superconductivity emerges from an interaction-induced metallic state that exhibits anomalous Hall effect, as observed in rhombohedral graphene and near the ν=23 fractional Chern insulator in twisted transition metal dichalcogenides. locked icon locked icon locked icon locked icon locked icon locked icon locked icon locked icon locked icon locked icon Physics Subject Headings (PhySH)Flat bandsFractionalizationSuperconductivityTopological phases of matterTopological superconductorsExact diagonalization
