反铁磁区 meaning in English

antiferromagnetic domain

Secondly , the influence of temperature and the number of qubits to the entanglement is discussed in the frame work of quantum heisenberg xx model . , the results show that the parity of the number of the qubit has the great influence to the properties of the entanglement . for the odd qubit system , the entanglement does n ' t exist in the anti - ferromagnetic region , and the critical temperature increases with the increase of the numbers
其次，以heisenbergxx链为模型，研究了多体情况下温度和量子位数对纠缠的影响，结果表明，量子位数的奇偶性对纠缠的性质有显著的影响，奇量子位系统在反铁磁区不存在对纠缠，且纠缠的临界温度随着量子位数的增加而升高；偶量子位系统在铁磁区和反铁磁区均存在对纠缠，而且纠缠的临界温度随着位数的增加而降低。
