我们研究了全息重整化群(RG)fl在其红外(IR)fi固定点以外的解析延拓。这种“跨IR”的flOW是描述黑洞内部物理的自然框架。首先，我们构造了一个单调的全息a-函数，它计算沿跨IRfl的自由度。利用这个函数，我们认为，当fl由于一个由Kasner奇点表示的跨IR端点而导致自由度“变薄”和消失时。然后，我们用TRANS-IRflOWS的语言重塑了研究得很好的量子信息探测器，fi指出，来自体积的纠缠和复杂性通常无法完全探测TRANS-IR，而来自作用的两点关联和复杂性通常以互补的方式做到这一点。
We study analytic continuations of holographic renormalization group (RG) flows beyond their infrared (IR) fixed points. Such “trans-IR” flows are a natural framework for describing physics inside of black holes. First, we construct a monotonic holographic a -function which counts degrees of freedom along a trans-IR flow. Using this function, we argue that the degrees of freedom “thin out” and vanish when flowing to a trans-IR endpoint, represented by a Kasner singularity. We then recast well-studied quantum information probes in the language of trans-IR flows, finding that entanglement and complexity from volume generally fail to fully probe the trans-IR while 2-point correlations and complexity from action generally do so in a complementary manner.
