Description
We investigate the gravitational wave signatures of a supercooled cosmic phase transition within a classically conformal Standard Model extension, where quark condensation can trigger symmetry breaking via spinodal decomposition instead of conventional bubble nucleation. By studying the amplification of scalar fluctuations in the linear regime, we estimate the associated scalar-induced stochastic gravitational wave background from the thermal inflation period preceding the phase transition. Lastly, we assess the prospects for their detection by comparing the predicted signals with the sensitivities of future gravitational wave experiments.
