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…
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…
The Anyon Zeno Effect
David F. Mross
Two anyons encircling each other acquire a quantized braiding phase that is independent of their spatial separation. We show that detecting this phase in a fractional quantum Hall…
Theory of Next-Generation Even-Denominator States
Misha Yutushui, David F. Mross
Even-denominator quantum Hall states are leading candidates for realizing non-Abelian topological orders, with the plateau in GaAs the first and most-studied examp…
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…
Triangular lattice models of the Kalmeyer-Laughlin spin liquid from coupled wires
Tingyu Gao, Niklas Tausendpfund, Erik L. Weerda +3
Chiral spin liquids (CSLs) are exotic phases of interacting spins in two dimensions, characterized by long-range entanglement and fractional excitations. We construct a local Hamil…
