For an opened Ising chain with an alternating magnetic field, the bipartite entanglement entropy decreases when the strength of the alternatingfield increases.
对于交替磁场中的伊辛链,所有的纠缠熵都随着交替磁场的增大而减小。

On top of that, the field generated by an alternating current interacts with the ground more strongly than it does with the air.
