Spin density matrix for neutral mesons in a pion gas in linear response theory
Yi-Liang Yin, Wen-Bo Dong, Cong Yi +1
We calculate the spin density matrix for neutral mesons from the spectral function and thermal shear tensor by Kubo formula in the linear response theory, which contributes to…

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…

A solvable model for spin polarizations with flow-momentum correspondence
Anum Arslan, Wen-Bo Dong, Guo-Liang Ma +2
We present an analytically solvable model based on the blast-wave picture of heavy-ion collisions with flow-momentum correspondence. It can describe the key features of spin polari…
