我们提出了一种全息方法,用于计算共形场论中的 Rényi 熵对平坦(或球形)纠缠表面周围小形状变形的响应。我们的策略采用变形双曲面背景中的应力张量单点函数,并将其与位移算子的两点函数中的系数相关联。我们获得了 d = 3、····、6 个时空维度的明确数值结果,并分析评估了一般维度中 Rényi 指数接近 1 和 0 的极限。我们使用我们的结果来扩展 1602.08493 的工作,并反驳文献中关于 Rényi 形状依赖性和扭曲算子的共形权重之间关系的一组猜想。我们还通过研究高斯-邦尼引力,将我们的分析扩展到体理论中导数的主导顺序之外。
We present a holographic method for computing the response of Rényi entropies in conformal field theories to small shape deformations around a flat (or spherical) entangling surface. Our strategy employs the stress tensor one-point function in a deformed hyperboloid background and relates it to the coefficient in the two-point function of the displacement operator. We obtain explicit numerical results for d = 3, · · · , 6 spacetime dimensions, and also evaluate analytically the limits where the Rényi index approaches 1 and 0 in general dimensions. We use our results to extend the work of 1602.08493 and disprove a set of conjectures in the literature regarding the relation between the Rényi shape dependence and the conformal weight of the twist operator. We also extend our analysis beyond leading order in derivatives in the bulk theory by studying Gauss-Bonnet gravity.
