论文摘要
在三个时空维度中，我们提出了经典全息张量网络（CHTN）通常协变的洛伦兹作用，因为在存在负宇宙常数的情况下，爱因斯坦 - 希尔伯特重力的全息降低。在本文中，首先，我们研究了洛伦兹行动在基础状态下的特性。接下来，基于CHTN的欧几里得作用，我们得出了CHTN中静止粒子引起的重力扰动，作为UNRUH效应。最后，我们将时空的全息图视为一项不平衡的第二定律，但要受一般协方差的影响。
In three spacetime dimensions, we propose a generally covariant Lorentzian action of the classicalized holographic tensor network (cHTN) as the holographic reduction of the Einstein-Hilbert action of gravity in the presence of a negative cosmological constant. In this article, first, we investigate the properties of this Lorentzian action in the ground state. Next, based on the Euclidean action of the cHTN, we derive the gravity perturbation induced by a massive particle at rest in the cHTN as the Unruh effect. Finally, we view our holographic formulation of spacetime as a non-equilibrium second law subject to general covariance.
