Local Spin Polarization in Anisotropic Gubser Flow: Suppression Mechanism and Formulation Dependence
Kenji Fukushima, Shi Pu, Dong-Lin Wang
We analytically study the longitudinal spin polarization in relativistic heavy-ion collisions using a perturbed Gubser flow solution. In the large-system-size limit, we derive anal…
Weyl anomaly induced transport in hydrodynamics
Shi-Zheng Yang, Jian-Hua Gao, Zuo-Tang Liang +4
We show that the Weyl (trace) anomaly gives rise to a new non-dissipative vector current in accelerated relativistic fluids. The anomaly uniquely fixes the second-order transport c…
Spin alignment of vector mesons in local equilibrium by Zubarev's approach
Shi-Zheng Yang, Xin-Qing Xie, Shi Pu +2
We compute the element of the spin density matrix, denoted as and called the spin alignment, up to the second order of the gradient expansion in local equilibrium by…
Corrections from space-time dependent electromagnetic fields to Wigner functions and spin polarization
Shi-Zheng Yang, Jian-Hua Gao, Shi Pu
We have derived the Wigner equations at global equilibrium with constant vorticity but space-time dependent electromagnetic fields up to second order in semiclassical expansion. We…
