蔡一夫 教授（中国科学技术大学）

Primordial black holes (PBHs) are widely considered as a hypothetical candidate of dark matter. However, the formation and astrophysical effects of PBHs still remain unclear. To gain the insights from the theoretical perspective, we recently proposed a novel mechanism of the sound speed resonance (SSR) cosmology that produces PBHs efficiently. I will briefly review the PBHs and the SSR mechanism and summarize what we have learned in this subject so far. I will also introduce the recent work on the application of the SSR mechanism into the stochastic gravitational waves which are expected to be a new probe for new physics in the early universe.

图 | 蔡一夫Yi-Fu Cai is a professor of physics and astronomy at the University of Science and Technology of China (USTC). He received the PhD degree in theoretical physics at the Institute of High Energy Physics in 2010. He worked as a postdoc at Arizona State University and McGill University until 2015. He was selected into the Chinese National Youth Talents Program in 2015 and became a faculty at USTC. His particle cosmology group at USTC is responsible for the scientific goals of the AliCPT project associated with cosmological models. His research focuses on fundamental questions for cosmology, namely, the big bang singularity, the origin and destiny of the universe, the cosmological perturbation theory and the CMB theory.
