Topological order in a 3D toric code at finite temperature
Claudio Castelnovo, Claudio Chamon
We study topological order in a toric code in three spatial dimensions, or a 3+1D Z_2 gauge theory, at finite temperature. We compute exactly the topological entropy of the system,…

Entanglement and topological entropy of the toric code at finite temperature
C. Castelnovo, C. Chamon
We calculate exactly the von Neumann and topological entropies of the toric code as a function of system size and temperature. We do so for systems with infinite energy scale separ…
