摘要

The one-dimensional 3-spin couplings and 2-spin competing many-body interactions with magnetic fields are an interesting field in quantum system, which is theoretically analysed in an experimental configuration. In this paper, we study the physical observable information for one-dimensional competing many-body interactions. The figure for symmetry broken state density, local order parameter, scaling of entanglement entropy is shown. The results agree with the phase diagram.
