Abstract
The present paper investigates the spin-1/2 XX model with three-spin interaction (TSI) from a view point of
bipartite entanglement. The three-spin system is initially chosen by well-known W entangled state. By analyzing
the time-dependency of the concurrence between the nearest and the next-nearest neighbor pair of spins, we
show that where the quantum phase transition (QPT) of the infinite-size system might happen and can be
observed, even from the short-time dynamics of such a finite spin system.
