Abstract

We generalize the KK matrix formulation to non-trivial non-Abelian families of 2+1D topological orders. Given a topological order C\mathcal C, any topological order in the same non-Abelian family as C\mathcal C can be efficiently described by a=(aI)\boldsymbol{a}=(a_I) where aIa_I are Abelian anyons in C\mathcal C, together with a symmetric invertible matrix KK, KIJ=kIJtaI,aJK_{IJ}=k_{IJ}-t_{a_I,a_J} where kIJk_{IJ} are integers, kIIk_{II} are even and taI,aJt_{a_I,a_J} are the mutual statistics between aI,aJa_I,a_J. In particular, when C\mathcal C is a root whose rank is the smallest in the family, KK becomes an integer matrix. Our results make it possible to generate the data of large numbers of topological orders instantly.
