Important Notice: Hotel reservations for participants will be arranged collectively by the organizers. However, except for invited speakers, accommodation costs must be paid by the individual participants. We kindly ask that you refrain from making your own hotel bookings. In addition, as this workshop is still awaiting final approval from the university, please do not purchase airline tickets until further notice.
Overview:
Rapid advances in cosmological observation programs, including AliCPT, CPTA, TianQin, and Taiji, are making it increasingly feasible to test fundamental ideas in early-universe physics, gravitation, and particle physics. In this context, theoretical research must move beyond the study of isolated models toward a more unified understanding of inflation, primordial black holes, early-universe phase transitions, the dark sector, and modified gravity, all of which are linked through multiple observational probes such as the CMB, pulsar timing, gravitational waves, and large-scale structure. This workshop aims to bring together researchers working on theoretical aspects and precision predictions in order to clarify the structure and interconnections of rapidly developing topics, including primordial black holes, induced gravitational waves, cosmological collider physics, black hole superradiance, and gravitational waves generated by cosmological phase transitions.
The workshop will also promote substantive exchange between leading international scholars and established and early-career researchers in China, helping to sharpen the key scientific questions likely to define the next stage of early-universe research. Jointly organized by the Southwest Center for Theoretical Physics at Chongqing University and the Center for Theoretical Physics of the Universe at the Institute for Basic Science in Korea, it will provide a high-level international forum for discussing theoretical mechanisms in the early universe and their observational signatures. By deepening collaboration and bringing together leading researchers from major institutions in China and abroad, the meeting will strengthen the theoretical foundations needed for future observational progress and support the continued development of cosmology and gravitation research in southwestern China.
