论文摘要
在本文中，根据ADS/BCFT处方，我们构建了针对具有边界（BCFTS）的系统双重的三维重力的时间依赖性解。可以在量子淬灭的描述中在一阶相变的动态或更普遍的情况下讨论此类解决方案。例如，我们应用全息模型来计算与欧几里得气泡成核相对应的局部淬火的纠缠熵的动力学。就像在已知的1+1 CFT示例中，局部切割和胶水淬灭一样，全息纠缠熵随时间增长，并以正确的通用系数的时间增长。但是，在气泡猝灭中，该行为在晚期是不同的。广告/BCFT模型在晚期表现出相关性和饱和度的轻度传播。我们还在有限温度下找到了熵的分析公式。在后一种情况下，初始对数生长之后是中间时间的线性定律。
In this paper we construct time-dependent solutions of three-dimensional gravity in AdS space dual to systems with boundaries (BCFTs), following the AdS/BCFT prescription. Such solutions can be discussed in the context of the dynamics of first order phase transitions, or more generally, in the description of quantum quenches. As an example, we apply the holographic model to calculate the dynamics of the entanglement entropy of a local quench corresponding to a nucleation of a Euclidean bubble. As in the known 1+1 CFT examples of local cut and glue quenches, the holographic entanglement entropy grows logarithmically with time with the correct universal coefficient. However, in the bubble quench, the behavior is different at late times. The AdS/BCFT model exhibits the light-cone spreading of correlations and saturation at late times. We also find an analytical formula for the entropy at finite temperature. In the latter case the initial logarithmic growth is followed by the linear law at intermediate times.
