Orbitally tuned composite-fermion metal-to-superfluid transitions
Ravi Kumar, Tomer Firon, André Haug +6
The effective interaction between composite fermions, set entirely by the Coulomb potential and the underlying electronic Landau level orbitals, can stabilize exotic fractional qua…

Interaction-driven quantum phase transitions between topological and crystalline orders of electrons
André Haug, Ravi Kumar, Tomer Firon +5
Topological and crystalline orders of electrons both benefit from enhanced Coulomb interactions in partially filled Landau levels. In bilayer graphene (BLG), the competition betwee…
