Probing chiral topological states with permutation defects
Yarden Sheffer, Ruihua Fan, Ady Stern +2
The hallmark of two-dimensional chiral topological phases is the existence of anomalous gapless modes at the spatial boundary. Yet, the manifestation of this edge anomaly within th…
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…
Extracting topological spins from bulk multipartite entanglement
Yarden Sheffer, Ady Stern, Erez Berg
We address the problem of identifying a 2+1d topologically ordered phase using measurements on the ground-state wavefunction. For non-chiral topological order, we describe a series…
Realizing string-net condensation: Fibonacci anyon braiding for universal gates and sampling chromatic polynomials
Zlatko K. Minev, Khadijeh Najafi, Swarnadeep Majumder +5
The remarkable complexity of the vacuum state of a topologically-ordered many-body quantum system encodes the character and intricate braiding interactions of its emergent particle…
