Topological aspects of the critical three-state Potts model
Robijn Vanhove, Laurens Lootens, Hong-Hao Tu +1
We explore the topological defects of the critical three-state Potts spin system on the torus, Klein bottle and cylinder. A complete characterization is obtained by breaking down t…
A tensor version of the quantum Wielandt theorem
Mateusz Michałek, Tim Seynnaeve, Frank Verstraete
We prove boundedness results for the injectivity regions for PEPS. Our result is a higher-dimensional generalization of the quantum Wielandt inequality.
Entanglement Rates and the Stability of the Area Law for the Entanglement Entropy
Michaël Mariën, Koenraad M. R. Audenaert, Karel Van Acoleyen +1
We prove a conjecture by Bravyi on an upper bound on entanglement rates of local Hamiltonians. We then use this bound to prove the stability of the area law for the entanglement en…
