量子纠缠第一定律的新发展

Novel Aspects of the Extended First Law of Entanglement

Felipe Rosso, Andrew Svesko

摘要:

利用AdS/CFT,我们已经推导出了一个在Minkowski中将真空简化为球的扩展的纠缠第一定律。该陈述不仅包括扰动的状态,但也共形场论(CFT),通过广义中心荷的变化。我们澄清了一些以前忽视的微妙之处,并使用简单的参数,以推广以前的推导任意重力理论的散装以及新的地区的边界CFT。我们的建设也适用于二维散装理论,并承认一个有趣的扩展为三维散装,提供了一个奇怪的结果,在扩展的黑洞热力学的热力学体积。我们讨论了未来的前景,关于扩展的纠缠第一定律。

英文摘要:

Using AdS/CFT an extended first law of entanglement has been previously derived for the vacuum reduced to a ball in Minkowski. The statement not only includes perturbations of the state but also of the conformal field theory (CFT), via variations of the generalized central charge. We clarify some subtleties previously overlooked and use simple arguments to generalize prior derivations to arbitrary gravity theories in the bulk as well as new regions in the boundary CFT. Our construction also applies to two-dimensional bulk theories and admits an interesting extension for a three-dimensional bulk, providing a curious result regarding the thermodynamic volume in extended black hole thermodynamics. We discuss future prospects regarding the extended first law of entanglement.
