Abstract

We study holographic subregion complexity in a moving strongly coupled plasma in dimensions d=2, 3, 4, which is holographically dual to a boosted black brane metric in a higher dimensional geometry. The proposal we employ is the one that identifies the complexity of a mixed state by the volume of codimensional-one hypersurface enclosed by Hubeny-Rangamani-Takayanagi surface. Using the finite difference method, the numerical calculations reveal that temperature, velocity, and subregion length all have an increasing effect on holographic subregion complexity. For arbitrary values of temperature and subregion length, as velocity approaches its relativistic upper limit, holographic subregion complexity exhibits a divergence. This divergence behavior observed in d=2, 3, 4 seems to demonstrate a universal behavior and is characterized by the Lorentz factor squared, γ2.

移动强耦合等离子体中的全息子区域复杂性

研究了一维d= 2,3,4的运动强耦合等离子体的全息子域复杂度，该子域复杂度是高维几何中增强黑膜度量的全息对偶。我们采用的建议是通过Hubeny-Rangamani-Takayanagi曲面包围的co维一超曲面的体积来识别混合状态的复杂性。利用有限差分方法进行了数值计算，结果表明温度、速度和子区域长度对全息子区域复杂度的影响均呈递增趋势。对于任意温度和子区长度，当速度接近其相对论性上限时，全息子区复杂性呈现发散。在d= 2,3,4中观察到的散度行为似乎证明了一种普遍的行为，并以洛伦兹因子的平方γ2为特征。2025年由美国物理学会出版
