论文摘要
在最近的一些弹圈猜想的驱动下，我们研究了一个暗能量的模型，其中典型的轴法由于其与U（1）或SU（1）或SU（2）仪表场的相互作用而在陡峭的潜力中缓慢滚动。这种相互作用产生的量规场可以生成一个随机引力波背景，其频率在$ f \ sim \ left范围内（10^{ - 16} -10^{-10^{ - 14} \ right）\; {\ rm Hz} $。在此范围内，可以通过CMB光谱畸变探测此范围内的重力波。我们表明，仅在非常有利的参数选择下，该模型中产生的信号的幅度高于可检测性的水平。
Motivated by some of the recent swampland conjectures, we study a model of dark energy, in which a quintessence axion slowly rolls in a steep potential due to its interactions with a U(1) or an SU(2) gauge field. The gauge fields produced by this interaction can generate a stochastic gravitational wave background with frequencies in the range $f \sim \left(10^{-16} - 10^{-14}\right)\; {\rm Hz}$. Gravitational waves in this range can in principle be probed by CMB spectral distortions. We show that the amplitude of the signal produced in this model is above the level for detectability only under very favourable choices of parameters.
