Bubble wall velocity from Kadanoff-Baym equations: fluid dynamics and microscopic interactions
Michael J. Ramsey-Musolf, Jiang Zhu
We establish a first principles, systematic framework for determining the bubble wall velocity during a first order cosmological phase transition. This framework, based on non-loca…

Confinement and Chiral Phase Transitions: The Role of Polyakov Loop Kinetics Terms
Banghui Hua, Jiang Zhu
We studied a crucial but often oversimplified ingredient in predicting gravitational-wave signals from QCD-type phase transitions: the kinetic term of the Polyakov loop. For the fi…

VacuumTunneling: A package to solve bounce equation with renormalization factor
Banghui Hua, Jiang Zhu
The Vacuum tunneling rate from the effective action is a key to studying the cosmological first-order phase transition(FOPT). One solid way to compute the is to start wit…
