FRW时空中化学势辅助的粒子产生

Chemical-Potential-Assisted Particle Production in FRW Spacetimes

Chon Man Sou, Xi Tong, Yi Wang

摘要:

我们分析了化学势辅助下的引力粒子产生。利用均匀平滑的斯托克斯线方法和Borel求和,我们深入了解细粒度的历史增强粒子的生产。给出了描述自旋1和自旋1/2粒子在不同FRW时空中产生量、时间和宽度的解析/半解析公式。我们的工作也作为一个具体的示范均匀光滑斯托克斯线方法应用于宇宙学。

英文摘要:

We analyze gravitational particle production assisted by chemical potential. By utilizing the uniformly smoothed Stokes-line method and Borel summation, we gain insight into the fine-grained history of enhanced particle production. Analytic/semi-analytic formulae describing the production amount, time and width are obtained for both spin-1 and spin-1/2 particles in various FRW spacetimes. Our work also serves as a concrete demonstration of the uniformly smoothed Stokes-line method applied to cosmology.
