论文摘要
基于流动方程全息法的扰动扩展，计算了对弱和局部相互作用的弱点和局部相互作用fermions的最小和局部相互作用fermions的区域定律的校正。一维情况和二维情况的明确计算（同样是在更高维度上）表明，对互动强度最多$ u^2 $纠缠的非相互作用费物的纠缠熵的领先校正不会改变扩展，但仅会影响领先的对数术语乘以quasipart cuasipart sipue quasipartipe cuasipate sipue quasipate sipue quasipate sipue quasipate sipue quasipart cy quasipate sipue quasipaltipe sipue quasipate sipue。还存在针对该地区法的术语领导。它与$ u^2 $在交互强度上成正比，并与系统大小线性缩放。
The correction to the area law for the bipartite min-entanglement entropy of weakly and locally interacting fermions is calculated based on a perturbative extension of the flow equation holography method. Explicit calculations for the one- and two-dimensional case (and similarly for higher dimensions) show that the leading correction to the entanglement entropy of non-interacting fermions up to $U^2$ in the interaction strength does not change the scaling, but only affects the pre-factor of the leading logarithmic term multiplying it by the quasiparticle residue. A term sub-leading to the area law is also present. It is proportional to $U^2$ in the interaction strength and scales linearly with the system size.
