Exact expectation values in a boost-invariant fluid of Dirac fermions with finite spin density
Andrea Palermo, Daniele Roselli
We study a boost-invariant, out-of-equilibrium fluid of non-interacting Dirac fermions with a finite canonical spin potential. After solving the Dirac equation in Milne coordinates…

Freezeout at constant energy density and spin polarization in heavy-ion collisions
Andrea Palermo, Masoud Shokri
Using the local equilibrium density operator, we develop a geometry-informed linear response theory that takes into account the parameterization of the freezeout hypersurface befor…

Initial conditions and bulk viscosity effects on polarization in high-energy heavy ion collisions
Andrea Palermo
The spin polarization is a crucial probe of the gradients of velocity and temperature in the quark-gluon plasma generated in heavy-ion collisions. However, it is still not sys…
