de Sitter时空中的振铃

Ringing in de Sitter spacetime

Alex Buchel

摘要:

流体力学是描述量子场论向平衡态弛豫的普适有效理论。德西特时空中的大质量QFT永远不会处于平衡状态。我们使用全息规范理论/引力对应来描述QFT弛豫到其Bunch-Davies真空-其晚期动力学的吸引子。具体来说,我们计算模拟的拟正规模式描述的全息玩具模型QFT在德西特放松。

英文摘要:

Hydrodynamics is a universal effective theory describing relaxation of quantum field theories towards equilibrium. Massive QFTs in de Sitter spacetime are never at equilibrium. We use holographic gauge theory/gravity correspondence to describe relaxation of a QFT to its Bunch-Davies vacuum - an attractor of its late-time dynamics. Specifically, we compute the analogue of the quasinormal modes describing the relaxation of a holographic toy model QFT in de Sitter.
