本文通过IIB型全息对偶研究禁闭多电荷AdS孤子背景下的Krylov扩散复杂度,利用探针粒子固有动量提议分析径向与旋转下落轨迹,数值揭示复杂度振荡行为。
AI 中文摘要
我们研究了一个IIB型解的的全息扩散复杂度,该解对偶于$\mathcal{N} = 4$ SYM的一种形变,该形变在红外流至一个禁闭的(2+1)维超对称理论。我们使用了将局部算符的扩散复杂度变化率与体空间中下落探针粒子的固有动量联系起来的提议。我们分析了两种情况:一个径向落下的探针粒子,以及一个在具有守恒角动量的同时径向落下并旋转的探针。我们详细阐述了在存在守恒Noether荷的情况下,如何使用Routhian定义固有坐标。探针的轨迹通过数值方法进行了研究,揭示了复杂度的振荡行为。
英文摘要
We study holographic spread complexity for a Type IIB solution dual to a deformation of $\mathcal{N} = 4$ SYM that flows to a confining (2+1)-dimensional supersymmetric theory in the IR. We use the proposal that relates the rate of change of spread complexity of local operators with the proper momentum of an infalling probe particle in the bulk. We analyse two cases: a probe particle falling radially and a probe falling radially while rotating with conserved angular momentum. We elaborate on how to define the proper coordinate in the presence of a conserved Noether charge using the Routhian. The trajectories for the probes were studied numerically, revealing an oscillatory behaviour of the complexity.
