AI 中文摘要
由满足零能量条件（NEC）的物质所支持的类空奇点预计会落入别林斯基 - 哈拉特尼科夫 - 利夫希茨（BKL）范式。我们表明，全息术中对NEC的可控违反可导致不同的黑洞内部。在与强耦合非厄米$\mathcal{PT}$对称量子场论对偶的全息模型中，我们在其实的、$\mathcal{PT}$恢复相内发现了一种新的非卡斯纳 regime。深层内部几何描述了一个经历超加速膨胀并接近小撕裂的各向同性FLRW宇宙学。该 regime在双侧重算子关联函数上留下特征印记，使其能与标准卡斯纳内部区分开来。我们的构造为小撕裂宇宙学提供了具体的全息实现，并为小撕裂/CFT对应奠定了基础，其中此类宇宙学 regime可通过非厄米量子场论中的可观测量来探索。
英文摘要
Spacelike singularities supported by matter satisfying the null energy condition (NEC) are expected to fall within the Belinski--Khalatnikov--Lifshitz (BKL) paradigm. We show that controlled violations of the NEC in holography can lead to different black hole interiors. In a holographic model dual to a strongly coupled non-Hermitian $\mathcal{PT}$-symmetric QFT, we uncover a novel non-Kasner regime within its real, $\mathcal{PT}$-restored phase. The deep-interior geometry describes an isotropic FLRW cosmology undergoing super-accelerated expansion and approaching a Little Rip. This regime leaves a characteristic imprint on two-sided heavy-operator correlators, allowing it to be distinguished from a standard Kasner interior. Our construction provides a concrete holographic realization of a Little Rip cosmology and lays the groundwork for a Little Rip/CFT correspondence, in which such cosmological regimes can be explored through observables in a non-Hermitian quantum field theory.
