Electrostatically stabilized surface flat bands in rhombohedral graphite at zero displacement field
Kryštof Kolář, Andrea F. Young, Cyprian Lewandowski
Rhombohedral (ABC-stacked) multilayer graphene hosts interaction-driven phases enabled by surface flat bands at large displacement fields. In thick flakes, however, strong screenin…

Tunneling signatures of interband coherence in dilute exciton condensates
Kryštof Kolář, Felix von Oppen
We theoretically investigate signatures of exciton condensation and the underlying interband coherence in scanning tunneling microscopy. We consider both monolayer and bilayer cond…
