Phase-transition sound of inflation at gravitational waves detectors
It is well-known that the first-order phase transition (PT) will yield a stochastic gravitational waves (GWs) background with a peculiar spectrum. However, we show that when such a PT happened during the primordial inflation, the GWs spectrum brought by the PT will be reddened, which thus records th...
