Relation between two measures of entanglement in spin-1/2 and spinless fermion quantum chain systems
Xiao-Feng Qian, Z. Song
The concepts of concurrence and mode concurrence are the measures of entanglement for spin-1/2 and spinless fermion systems respectively. Based on the Jordan-Wigner transformation,…

Characterizing entanglement by momentum-jump in the frustrated Heisenberg ring at quantum phase transition
Xiao-Feng Qian, Tao Shi, Ying Li +2
We study the pairwise concurrences, a measure of entanglement, of the ground states for the frustrated Heisenberg ring to explore the relation between entanglement and quantum phas…
