Rhombohedral Graphene: A Tale of Many Crystals
Ahmed Abouelkomsan, Filippo Gaggioli, Daniele Guerci +1
Experiments on rhombohedral graphene have uncovered an extraordinary wealth of correlated quantum phases - from chiral superconductors to electronic crystals - all within a single…
Topological superconductivity with emergent vortex lattice in twisted semiconductors
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
The coexistence of superconductivity and fractional quantum anomalous Hall (FQAH) effect has recently been observed in twisted MoTe and theoretically demonstrated in a model of…
From Fractionalization to Chiral Topological Superconductivity in a Flat Chern Band
Daniele Guerci, Ahmed Abouelkomsan, Liang Fu
We show that interacting electrons in a flat Chern band can form, in addition to fractional Chern insulators, a chiral -wave topological superconductor that hosts neutral Majora…
Spontaneous vortex-antivortex lattice and Majorana fermions in rhombohedral graphene
Filippo Gaggioli, Daniele Guerci, Liang Fu
The discovery of superconducting states in multilayer rhombohedral graphene with spin and valley polarization has raised an interesting question: how does superconductivity cope wi…
