Partition function of the Kitaev quantum double model
Anna Ritz-Zwilling, Benoît Douçot, Steven H. Simon +2
We compute the degeneracy of energy levels in the Kitaev quantum double model for any discrete group on any planar graph forming the skeleton of a closed orientable surface of…

Topological and nontopological degeneracies in generalized string-net models
Anna Ritz-Zwilling, Jean-Noël Fuchs, Steven H. Simon +1
Generalized string-net models have been recently proposed in order to enlarge the set of possible topological quantum phases emerging from the original string-net construction. In…

Finite-temperature properties of string-net models
Anna Ritz-Zwilling, Jean-Noël Fuchs, Steven H. Simon +1
We consider a refined version of the string-net model which assigns a different energy cost to each plaquette excitation. Using recent exact calculations of the energy-level degene…
