Critical temperature for entanglement transition in Heisenberg models
Hongchen Fu, Allan I Solomon, Xiaoguang Wang
We study thermal entanglement in some low-dimensional Heisenberg models. It is found that in each model there is a critical temperature above which thermal entanglement is absent.

Spin squeezing criterion with local unitary invariance
A. R. Usha Devi, Xiaoguang Wang, Barry C Sanders
We propose a new spin squeezing criterion for arbitrary multi-qubit states that is invariant under local unitary operations. We find that, for arbitrary pure two-qubit states, spin…
