标题： The irreversible relaxation of inflation

摘要： 基于之前对嵌入de Sitter空间的开放系统不可逆演化的Markov主方程分析的结果，我们在宇宙学Friedmann方程中加入了一个物理浴存在（温度为 $T_{\rm dS} = h / 2 \pi$）的贡献，其中 $h$ 是哈勃参数。 我们表明，这提供了一种机制，使宇宙学常数能够不可逆地弛豫，并且实现了通货膨胀的优雅退出，无需后续的再加热过程。 通货膨胀期间的热粒子产生会给出绝热、高斯分布且近似尺度不变的宇宙扰动。 因此，我们得到了通货膨胀的主要特征，而无需引入任何 inflaton 势能。 为了澄清这些结果的热力学解释，我们考虑了这种不可逆弛豫与量子光学中超荧光之间的类比。 显示英文摘要

摘要： Based on the results of a previous analysis of the Markovian master equation for the irreversible evolution of an open system embedded in de Sitter space, we include in the cosmological Friedmann equations a contribution from the presence of a physical bath at temperature $T_{\rm dS} = h / 2 \pi$, where $h$ is the Hubble parameter. We show that this provides a mechanism for the irreversible relaxation of the cosmological constant and a graceful exit to inflation, without need for subsequent reheating. Thermal particle production during inflation gives adiabatic, Gaussian, and approximately scale-invariant cosmological perturbations. We thus obtain the main features of inflation without any inflaton potential. To clarify the thermodynamic interpretation of these results, we consider the analogy of this irreversible relaxation to superfluorescence in quantum optics.
