摘要：
We investigate how an appropriate choice of the external field allows one to control many-body entanglement characterized by spin squeezing and the reciprocal of mean quantum Fisher information per particle (RMQFI). By adopting frozen-spin approximation, we succussed in obtaining analytical expressions of the spin squeezing parameter and RMQFI. The stronger external field induces stronger squeezing, the smaller value of RMQFI and the larger period.
