During the early universe\, many interesting physic al processes could generate gravitational waves\, which were usually assoc iated with new physics beyond the standard model. This opens up a new obse rvational window for humanity to further uncover the origins of the univer se and its matter content. These gravitational waves are generated at diff erent epochs and propagate through the cosmic history until the present \, which are redshifted to different frequency bands. In the recent futu re\, various gravitational wave detection projects are planned\, includin g CMB-S4\, LiteBIRD\, BICEP3/Keck Array\, AliCPT utilizing the B-mode pola rization of the cosmic microwave background radiation\; NANOGrav\, EPTA\, PPTA\, CPTA using pulsar timing arrays\; LISA\, Taiji\, TianQin utilizing space-based gravitational wave interferometers\; and ET\, BBO for ground-b ased gravitational wave interferometers.\n\nRecently\, the NANOGrav\, EPTA \, and CPTA jointly announced strong evidence for the existence of a nan ohertz stochastic gravitational wave background. This has reignited our in terest in gravitational waves produced in the early universe.\n\nIn order to further advance research in relevant fields\, we held the first Interna tional Workshop on Gravitational Waves and the Early Universe\, which attr acted more than 100 scholars from over a dozen domestic and international research institutions and universities. During the three days of the confe rence\, participants engaged in extensive discussions on recent developmen ts in observations and theory.\n\nWe are glad to announce that the 2nd Int ernational Workshop on Gravitational Waves and the Early Universe will be held from April 8th to 11th\, 2024.
