标题： Primordial perturbations from inflation

摘要： 我回顾了由单个标量场驱动的慢滚暴胀产生的绝热标量和张量扰动的标准分析，然后讨论了近期关于非绝热模在暴胀期间和之后作用的研究。 与绝热模相关的等曲率扰动可能在多场暴胀期间产生，并将提供有关早期宇宙物理的重要信息。 目前的数据并未排除相关等曲率扰动的显著贡献，但应通过未来的观测进行检测或排除。 显示英文摘要

摘要： I review the standard analysis of adiabatic scalar and tensor perturbations produced by slow-roll inflation driven by a single scalar field, before going on to discuss recent work on the role of non-adiabatic modes during and after inflation. Isocurvature perturbations correlated with adiabatic modes may be produced during multi-field inflation and would give valuable information about the physics of the early universe. A significant contribution from correlated isocurvature perturbations is not ruled out by present data, but should be either detected or ruled out by future observations.
