标题： Entanglement Suppression Due to Black Hole Scattering

摘要： 我们考虑二维共形场理论中纠缠熵的演化，该理论具有全息对偶。 具体而言，我们感兴趣的是由纯态（局部算符）和混合态局部淬火组合产生的激发态类别。 我们采用一种方法，使我们能够解析地确定完整的时间演化。 虽然单个局部算符的插入相对于真空会产生纠缠熵的对数时间轮廓，但我们发现，在存在混合态淬火的情况下，这种增长被大大抑制，使其变为时间不变的常数波动。 抑制的程度取决于淬火的相对位置以及与淬火相关的正则化参数的比值。 这项工作揭示了涉及黑洞的引力散射有趣特性。 显示英文摘要

摘要： We consider the evolution of entanglement entropy in a two-dimensional conformal field theory with a holographic dual. Specifically, we are interested in a class of excited states produced by a combination of pure-state (local operator) and mixed-state local quenches. We employ a method that allows us to determine the full time evolution analytically. While a single insertion of a local operator gives rise to a logarithmic time profile of entanglement entropy relative to the vacuum, we find that this growth is heavily suppressed in the presence of a mixed-state quench, reducing it to a time-independent constant bump. The degree of suppression depends on the relative position of the quenches as well as the ratio of regularization parameters associated with the quenches. This work sheds light on the interesting properties of gravitational scattering involving black holes.
