摘要:
在这项工作中,我们研究了具有守恒角动量的$\textrm{T}\bar{\textrm{T}}$形变全息CFT$_2$(二维共形场论)中的纠缠结构。我们利用共形微扰论,在大中心电荷极限下计算了$\textrm{T}\bar{\textrm{T}}$形变导致的纠缠熵和反射熵的领头阶修正。在由带有限径向截断的旋转BTZ黑洞描述的对偶体视角下,我们计算了全息纠缠熵和纠缠楔形截面,并观察到在形变参数取小值时,其与我们的场论计算结果完全一致。
英文摘要:
In this work, we investigate the entanglement structure in a $\textrm{T}\bar{\textrm{T}}$-deformed holographic CFT$_2$ with a conserved angular momentum. We utilize conformal perturbation theory to compute the leading order correction to the entanglement entropy and the reflected entropy due to the $\textrm{T}\bar{\textrm{T}}$ deformation in the limit of large central charge. In the dual bulk perspective described by a rotating BTZ black hole with a finite radial cut-off, we compute the holographic entanglement entropy and the entanglement wedge cross-section and observe perfect agreement with our field theoretic computation for small values of the deformation parameter.
