Q型热测井球的归宿
Fate of thermal log type Q balls
摘要：
利用晶格模拟研究了热对数势中$Q$球的时间演化。随着温度的降低，由于宇宙膨胀，热对数项的潜力最终克服了质量项，我们确认，$Q$球变换从厚壁型到薄壁型的辐射修正系数的质量项，最近建议。此外，我们发现，当$Q$球溶液消失时，$Q$球最终“熔化”。我们还讨论了这种现象对引力波从$Q$球形成的可探测性的影响。
英文摘要：
We study time evolution of the $Q$ ball in thermal logarithmic potential using lattice simulations. As the temperature decreases due to the cosmic expansion, the thermal logarithmic term in the potential is eventually overcome by a mass term, and we confirm that the $Q$ ball transforms from the thick-wall type to the thin-wall type for a positive coefficient of radiative corrections to the mass term, as recently suggested. Moreover, we find that the $Q$ ball finally "melts down" when the $Q$-ball solution disappears. We also discuss the effects of this phenomenon on the detectability of gravitational waves from the $Q$-ball formation.
