چکیده
|
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.
