A dynamical Toric Code model with fusion and de-fusion
Bruno Nachtergaele, Nicholas E. Sherman
We introduce a two-parameter family of perturbations of Kitaev's Toric Code Model in which the anyonic excitations acquire an interesting dynamics. We study the dynamics of this mo…

Nonzero temperature Entanglement Negativity of quantum spin models: Area law, Linked Cluster Expansions and Sudden Death
Nicholas E. Sherman, Trithep Devakul, Matthew B. Hastings +1
We show that the bipartite logarithmic entanglement negativity (EN) of quantum spin models obeys an area law at all nonzero temperatures. We develop numerical linked cluster (NLC)…
