近日，比利时鲁汶大学理论物理研究所的Sergio E. Aguilar-Gutierrez及其研究团队取得一项新进展。经过不懈努力，他们揭示Schwarzschild-de Sitter space空间中的C=Anything和之字形效应。相关研究成果已于2024年3月12日在国际知名学术期刊《高能物理杂志》上发表。

该研究团队深入探究了激波源对Schwarzschild-de Sitter (SdS)空间在余维数-1的C=Anything (CAny)理论框架下的观测值影响。在此框架下，存在一组时间反演不变的观测值，无论是否受到激波源的影响，其早期和后期的增长率均保持一致。但当研究人员在弱引力耦合条件下引入激波时，发现后期的复杂性增长有所减少，这归因于与早期扰动的相互抵消，即所谓的之字形效应。

这一发现表明，SdS空间中的部分CAny观测值，其表现行为与反德西特黑洞中观测到的行为相似。研究人员认为，他们的研究成果可能为探索假定的量子力学理论提供新的方向。

Abstract: We investigate observables within the framework of the codimension-one C=Anything (CAny) proposal for Schwarzschild-de Sitter (SdS) space under the influence of shockwave sources. Within the proposal, there is a set of time-reversal invariant observables that display the same rate of growth at early and late times for a background with or without shockwave sources. Once we introduce shockwaves in the weak gravitational coupling regime, there is a decrease in the late-time complexity growth due to cancellations with early-time perturbations, known as the switchback effect. The result shows that some CAny observables in SdS may reproduce the same type of behavior found in anti-de Sitter black holes. We comment on how our results might guide us to new explorations in the putative quantum mechanical theory.
