Approximating the ground state of gapped quantum spin systems
Eman Hamza, Spyridon Michalakis, Bruno Nachtergaele +1
We consider quantum spin systems defined on finite sets equipped with a metric. In typical examples, is a large, but finite subset of Z^d. For finite range Hamiltonians wit…

Entanglement and ground states of gapped Hamiltonians
Spyridon Michalakis
We begin by deriving bounds for the entanglement of a spin with an (adjacent and non-adjacent) interval of spins in an arbitrary pure Finitely Correlated States (FCS). The bounds w…

Entanglement in Finitely Correlated Spin States
Spyridon Michalakis, Bruno Nachtergaele
We derive bounds for the entanglement of a spin with an (adjacent and non-adjacent) interval of spins in an arbitrary pure finitely correlated state (FCS) on a chain of spins of an…
