Steady-state topological order is defined via degeneracy and entropy in open-system Liouvillians, with models showing exponential splitting but algebraically closing gaps.
III A 4, Levin-Wen’s definition of topo- logical entropy is more suitable for characterizing topological order in open systems, and we use their definition for our cal- culation
