Using the results of lattice simulation, we show that preheating can
generate low-frequency Gravitational Waves (GWs) to be detectable within the
future GWs detectors such as BBO, DECIGO, PTA, AION-MAGIS, and CE (in MeV
- TeV ranges). We show that these stochastic GWs signals can act as a novel
probe for various Particle Physics Phenomenology in the Early Universe, such as
the origin of Dark Matter and the production of matter-antimatter asymmetry.
