This article will review quantum particle creation in expanding universes. The emphasis will be on the basic physical principles and on selected applications to cosmological models. The needed formalism of quantum field theory in curved spacetime will be summarized, and applied to the example of scalar particle creation in a spatially flat Universe. Estimates for the creation rate will be given and applied to inflationary cosmology models. Analog models which illustrate the same physical principles and may be experimentally realizable are also discussed.

宇宙粒子的产生：综述

本文将回顾膨胀宇宙中量子粒子的产生。重点将放在基本物理原理和宇宙模型的选定应用上。将总结弯曲时空中量子场论所需的形式，并将其应用于在空间平坦的宇宙中创建标量粒子的示例。将给出对创造率的估计并将其应用于暴胀宇宙学模型。还讨论了说明相同物理原理并且可以通过实验实现的模拟模型。
