Spin polarization of an expanding and rotating system
Nora Weickgenannt, Jean-Paul Blaizot
We study the longitudinal spin polarization of a relativistic fluid of massive spin-1/2 particles undergoing a boost-invariant expansion in the longitudinal direction and rotating…

Spin kinetic theory with a nonlocal relaxation time approximation
Nora Weickgenannt, Jean-Paul Blaizot
We present a novel relaxation time approximation for kinetic theory with spin which takes into account the nonlocality of particle collisions. In particular, it models the property…
