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…
