标题： Behind-the-horizon excitations from a single 2d CFT

摘要： 在这项工作中，我们考虑了在 [1708.06328] 中发现的非典型非平衡态，该状态在黑洞时空背景下通过全息理论表示事件视线后的激发。这一状态的特殊之处在于，当用一类低能算符探测时，它看起来像一个平衡态。首先，我们在中心荷很大的极限下使用一致化映射来重现这一性质，在这个过程中，我们能够推导出而不是假设近似的热物理现象。此外，在大中心荷和高能极限下，我们将这些激发视为轻算符代数GNS表示的共中心代数元素。我们不是解析延拓混合重-轻的欧几里得相关函数到洛伦兹相关函数，而是将欧几里得相关函数识别为GNS线性形式，并将洛伦兹相关函数解释为轻算符代数在GNS真空上的代表的真空期望值。 显示英文摘要

摘要： In this work, we consider the atypical non-equilibrium state found in [1708.06328] which holographically represents a behind-the-horizon excitation in a blackhole spacetime. The special feature of this state is that it looks like an equilibrium state when probed by a class of low-energy operators. First, we retrieve this property using the uniformization mapping in the limit of large central charge, in the process we are able to derive rather than presume approximate thermal physics. Furthermore, in the large-c and high-energy limit we realize these excitations as elements of the commutant algebra of a GNS-representation of the light operator algebra. Instead of analytically continuing a mixed heavy-light Euclidean correlator to a Lorentzian correlator, we identify the Euclidean correlator as a GNS-linear form and interpret the Lorentzian correlator as a vacuum expectation value of representatives of the light operator algebra on the GNS-vacuum.
