标题： Negative single-trace $T\bar T$ holography versus de Sitter holography

摘要： 在单迹元 $T\bar T$ 全息理论中，对于变形参数取负值的情况，与高能态相对偶的几何结构由一个奇异的紫外壁组成，该壁将红外区的黑洞弦与渐近线性标度时空分隔开。 在全息图中，这些黑洞弦对应于 $T\bar T$ 变形的 $CFT_2$ 对称乘积中的状态，其能量和动量在不同的块中被平均分配。 这种全息对偶的性质与提出的de Sitter全息原理具有引人入胜的相似之处。 本文展示了两者之间的类比关系。 特别是，当视界位置接近紫外壁时，会得到一个最大有限熵且温度无限高的状态。 另一方面，在极限情况下获得的几何结构的体温度较低。 这些性质与提出的空de Sitter全息理论中的性质完全相同。 显示英文摘要

摘要： In single-trace $T\bar T$ holography, for the negative sign of the deformation, the geometries dual to high energy states consist of a singular UV wall that separates black strings in the IR from an asymptotically linear dilaton spacetime. In the hologram, the black strings amount to states in a symmetric product of $T\bar T$ deformed $CFT_2$, whose energy and momentum are split equally among the different blocks. The properties of this holographic duality have intriguing similarities with the proposed principles of de Sitter holography. In this note, the analogy between the two is presented. In particular, as the horizon location approaches the UV wall, one obtains a state of maximum finite entropy and infinite temperature. On the other hand, the bulk temperature of the geometry obtained in the limit is small. These properties are identical to those proposed in empty de Sitter holography.
