The Chinese Pulsar Timing Array (CPTA) collaboration has recently reported the observational evidence of a stochastic gravitational wave background. In light of the latest CPTA observation, we aim at exploring the ability of CPTA in probing new physics. Specifically, we constrain the first-order cosmological phase transitions with CPTA data, and find that the constraining result is slightly tighter than that of NANOGrav's 12.5-yr data but weaker than NANOGrav's 15-yr data. Considering the possible complexity of gravitational wave sources, we give the constraint on a mixed scenario of cosmological phase transitions and astrophysical supermassive binary black holes. Our analysis suggests that CPTA has a great potential to probe fundamental physics in the near future.

QCD Axion Domain Walls from Super-Cooling First Order Phase Transition
A supercooled first-order phase transition near the QCD scale can briefly set the QCD axion into mini kinetic misalignment and, through bubble inhomogeneities, produce axion domain walls even without cosmic strings.

NANOGrav 15-year gravitational-wave signals from binary supermassive black-holes seeded by primordial black holes, and implications for the origins of Little Red Dots
A PBH abundance of 10^-14–10^-12 of CDM, with seed masses 1–10^3 M_sun, is fitted to the NANOGrav 15-year background via SMBH mergers, consistent with 21-cm limits.
