Chiral projected entangled-pair state with topological order
Shuo Yang, Thorsten B. Wahl, Hong-Hao Tu +2
We show that projected entangled-pair states (PEPS) can describe chiral topologically ordered phases. For that, we construct a simple PEPS for spin-1/2 particles in a two-dimension…

Slowest local operators in quantum spin chains
Hyungwon Kim, Mari Carmen Bañuls, J. Ignacio Cirac +2
We numerically construct slowly relaxing local operators in a nonintegrable spin-1/2 chain. Restricting the support of the operator to consecutive spins along the chain, we exh…
