Does this mean that Wen-Levin's string-net condensation gives rise directly to U(1) gauge bosons and electrons?
I don't have a complete grasp on the physical picture Wen is proposing, but I would guess that is what should happen in the limit that [tex]\Lambda \rightarrow 0 [/tex], i.e. as [tex] SU(2)_k \rightarrow SU(2) [/tex]
