我们提出了一个平均场的方法来分析多体系统的费米子在规范/引力对偶。我们在引力对偶中引入了一个非零的经典费米子场，我们称之为费米子的全息平均场。全息平均场考虑了体块中费米子的多体动力学。全息平均场的正则性条件明确地确定了化学势与密度之间的关系。我们的方法提供了一个新的框架，规范/重力对偶的有限密度系统的重子在禁闭阶段。
We propose a mean-field approach to analyze many-body systems of fermions in the gauge/gravity duality. We introduce a nonvanishing classical fermionic field in the gravity dual, which we call the holographic mean-field for fermions. The holographic mean-field takes account of the many-body dynamics of the fermions in the bulk. The regularity condition of the holographic mean-field fixes the relationship between the chemical potential and the density unambiguously. Our approach provides a new framework of gauge/gravity duality for finite-density systems of baryons in the confinement phase.
