Suppression of scalar perturbations due to a heavy axion
Kai-Ge Zhang, Jian-Feng He, Chengjie Fu +1
A fast-rolling axion can transfer its kinetic energy to gauge fields via the Chern-Simons coupling, leading to copious production of gauge quanta during inflation. The amplified ga…
Gravitational Waves from Gauge Quanta Produced during Inflation
Kai-Ge Zhang, Jian-Feng He, Chengjie Fu +1
A fast-rolling axion can transfer its kinetic energy to a gauge field via the Chern-Simons coupling, leading to copious production of gauge quanta, which can act as a source of gra…
Strong backreaction of gauge quanta produced during inflation
Jian-Feng He, Kai-Ge Zhang, Chengjie Fu +1
During inflation an axion field coupled to a gauge field through a Chern-Simons term can trigger the production of gauge quanta due to a tachyonic instability. The amplification of…
Chiral symmetry restoration and properties of Goldstone bosons at finite temperature
Yin-Zhen Xu, Si-Xue Qin, Hong-Shi Zong
We study chiral symmetry restoration by analyzing thermal properties of QCD's (pseudo-)Goldstone bosons, especially the pion. The meson properties are obtained from the spectral de…
Chiral phase transition inside a rotating cylinder within the Nambu--Jona-Lasinio model
Zheng Zhang, Chao Shi, Xiao-Tao He +2
We study the chiral phase transition inside a rotating cylinder within the framework of the Namb--Jona-Lasinio model. A spectral boundary condition is imposed to avoid faster than…
Chiral transition and the chiral charge density of the hot and dense QCD matter
Chao Shi, Xiao-Tao He, Wen-Bao Jia +3
We study the chirally imbalanced hot and dense strongly interacting matter by means of the Dyson-Schwinger equations (DSEs). The chiral phase diagram is studied in the presence of…
