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…

Linear response theory for spin alignment of vector mesons in thermal media
Wen-Bo Dong, Yi-Liang Yin, Xin-Li Sheng +2
We present a calculation of the spin alignment for unflavored vector mesons in thermalized quark-gluon plasma based on the Kubo formula in linear response theory. This is achieved…
