构建了铁磁系统的全息实现。在此基础上提出全息字典，得到了相关的热力学量，如磁化率、磁化率和自由能。该全息模型再现了平均场理论在临界温度附近的行为。在低温下，结果自动包含自旋波激发和传导电子的贡献。
A holographic realization for ferromagnetic systems has been constructed. Owing to the holographic dictionary proposed on the basis of this realization, we obtained relevant thermodynamic quantities such as magnetization, magnetic susceptibility, and free energy. This holographic model reproduces the behavior of the mean field theory near the critical temperature. At low temperatures, the results automatically incorporate the contributions from spin wave excitations and conduction electrons.
