Selective braiding of different anyons in the even-denominator fractional quantum Hall effect
Jehyun Kim, Amit Shaer, Ravi Kumar +6
Even-denominator quantum Hall states can host several types of anyons with distinct exchange statistics. Depending on the anyon type, exchanging two quasiparticles can impart a pha…
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…
Aharonov-Bohm Interference in Even-Denominator Fractional Quantum Hall States
Jehyun Kim, Himanshu Dev, Amit Shaer +9
Position exchange of non-Abelian anyons affects the quantum state of their system in a topologically-protected way. Their expected manifestations in even-denominator fractional qua…
