Query: Multi-impurity chiral Kondo model: correlation functions and anyon
  fusion rules   The multichannel Kondo model supports effective anyons on the partially
screened impurity, as suggested by its fractional impurity entropy. It was
recently demonstrated for the multi-impurity chiral Kondo model, that
scattering of an electron through the impurities depends on the anyon's total
fusion channel. Here we study the correlation between impurity-spins. We argue,
based on a combination of conformal field theory, a perturbative limit with a
large number of channels $k$, and the exactly solvable two-channel case, that
the inter-impurity spin correlation probes the anyon fusion of the pair of
correlated impurities. This may allow, using measurement-only topological
quantum computing protocols, to braid the multichannel Kondo anyons via
consecutive measurements.
