Global geometric entanglement in transverse-field XY spin chains: finite and infinite systems

Tzu-Chieh Wei, Smitha Vishveshwara, Paul M. Goldbart

The entanglement in quantum XY spin chains of arbitrary length is investigated via the geometric (measure of) entanglement. The emergence of entanglement is explained intuitively f…
