论文摘要
DS观察者因果楔形楔的平衡状态是热的，尽管现实的观察者只能部分进入状态。对他们来说，轻标量场的不平衡状态似乎以马尔可夫的方式进行热度化。我们通过制定系统的扩展来展示这一点，以追踪环境。例如，我们将$ O（λ）$校正计算为Starobinsky和Yokoyama的结果，用于$ λϕ^4 $理论的放松指数。
The equilibrium state of fields in the causal wedge of a dS observer is thermal, though realistic observers have only partial access to the state. To them, out-of-equilibrium states of a light scalar field appear to thermalize in a Markovian fashion. We show this by formulating a systematic expansion for tracing out the environment. As an example, we calculate the $O(λ)$ correction to the result of Starobinsky and Yokoyama for the relaxation exponents of $λϕ^4$ theory.
