一个简单的全息图方案为间隙淬火

A simple holographic scenario for gapped quenches

Esperanza Lopez, Guillermo Milans del Bosch

摘要:

我们构造引力背景对偶的相关耦合参数化的场论的家庭。它们结合了非平凡的标量场轮廓和裸奇点。裸奇点是保持沿边界方向的洛伦兹不变性所必需的。然而,通过在几何结构中引入红外截止来切除奇异性。发展了与红外边界相关联的全息字典。我们在两个不同的耦合值之间实现猝灭。这需要考虑在AdS边界和红外墙处的标量场的时间相关边界条件。

英文摘要:

We construct gravitational backgrounds dual to a family of field theories parameterized by a relevant coupling. They combine a non-trivial scalar field profile with a naked singularity. The naked singularity is necessary to preserve Lorentz invariance along the boundary directions. The singularity is however excised by introducing an infrared cutoff in the geometry. The holographic dictionary associated to the infrared boundary is developed. We implement quenches between two different values of the coupling. This requires considering time dependent boundary conditions for the scalar field both at the AdS boundary and the infrared wall.
