小宇宙弦环的标度解

Scaling solution for small cosmic string loops

Jorge V. Rocha

摘要:

在宇宙弦网络中,控制环数密度随时间演化的方程是一个由能量守恒决定的细致平衡。我们解决了这个方程,包括引力辐射效应,导致环收缩(并最终衰减)随着时间的推移。该解决方案的方法的缩放制度,其中总的能量密度在环路保持有限,收敛在红外和紫外线。

英文摘要:

The equation governing the time evolution of the number density of loops in a cosmic string network is a detailed balance determined by energy conservation. We solve this equation with the inclusion of the gravitational radiation effect which causes the loops to shrink (and eventually decay) as time elapses. The solution approaches a scaling regime in which the total energy density in loops remains finite, converging both in the infrared and in the ultraviolet.
