Distinct photon-ALP propagation modes
Qing-Hong Cao, Zuowei Liu, Jun-Chen Wang
Measurement of cosmic photons may reveal their propagation in the interstellar environment, thereby offering a promising way to probe axions and axion-like particles (ALPs). Numeri…
Bubble wall velocity from number density current in (non)equilibrium
Zi-Yan Yuwen, Jun-Chen Wang, Shao-Jiang Wang
Cosmological first-order phase transitions (FOPTs) serve as comprehensive probes into our early Universe with associated generations of stochastic gravitational waves and superhori…
General backreaction force of cosmological bubble expansion
Jun-Chen Wang, Zi-Yan Yuwen, Yu-Shi Hao +1
The gravitational-wave energy-density spectra from cosmological first-order phase transitions crucially depend on the terminal wall velocity of asymptotic bubble expansion when the…
General bubble expansion at strong coupling
Jun-Chen Wang, Zi-Yan Yuwen, Yu-Shi Hao +1
The strongly coupled system like the quark-hadron transition (if it is of first order) is becoming an active play yard for the physics of cosmological first-order phase transitions…
