AI总结:

本研究在“复杂性即任意量”提议下探究奇数维等角动量MP-AdS黑洞的广义全息复杂性,推导其局域晚期增长率、全局早期多类相变,提出面积定律与相图,定义形成复杂性并验证标度关系,且结果可推广至余维零可观测量。

摘要:

我们在“复杂性即任意量”(complexity equals anything)的提议框架下,探究了具有相等角动量的奇数维Myers-Perry渐近反德西特(MP-AdS)黑洞的广义全息复杂性。首先,我们通过求解广义协变体积泛函的极值,确定了余维一的广义体积复杂性。在局域层面,我们证明其晚期增长率与极值超曲面对应的临界动量相一致。在全局层面,我们发现早期复杂性存在多种相变,包括一阶、二阶和多临界相变。我们提出了一个面积定律和一张相图来适配这些相变行为,突出了黑洞角动量的影响。在零时刻,我们定义了形成过程的广义全息复杂性,并研究了其在大质量近极端MP-AdS黑洞和静态带电黑洞中的标度关系。我们发现,除了定义广义全息复杂性的标量泛函在真空极限或空间无穷远处为无穷大的情况外,形成过程的广义体积复杂性的标度行为与原始全息复杂性公式的标度行为保持一致。此外,我们证明这些发现可以推广应用到余维可观测量上。

英文摘要:

We explore the generalized holographic complexity of odd-dimensional Myers-Perry asymptotically Anti-de Sitter (MP-AdS) black holes with equal angular momenta within the ``complexity equals anything'' proposal. We begin by determining the codimension-one generalized volume complexity by finding the extremum of the generally covariant volume functional. Locally, we show that its late-time growth rate aligns with the critical momenta associated with the extremal hypersurfaces. Globally, we discover diverse phase transitions for the complexity at early times, including first-order, second-order, and multi-critical transitions. An area law and a phase diagram are proposed to adapt to these phase behaviours, highlighting the effects of the black hole's angular momentum. At zero time, we define the generalized holographic complexity of formation and examine its scaling relations for both large near-extremal MP-AdS black holes and static charged black holes. We find that the scaling behaviours of the generalized volume complexity of formation maintain uniformity with those of the original holographic complexity formulations, except in cases where the scalar functional defining the generalized holographic complexity is infinite in the vacuum limit or at spatial infinity. Additionally, we show that these findings can be applied to codimension-zero observables.
