Entanglement spectrum and boundary theories with projected entangled-pair states
Entanglement spectrum and boundary theories with projected entangled-pair states
In many physical scenarios, close relations between the bulk properties of quantum systems and theories associated to their boundaries have been observed. In this work, we provide an exact duality mapping between the bulk of a quantum spin system and its boundary using Projected Entangled Pair States (PEPS). This duality …
