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…

An improved formula for Wigner function and spin polarization in a decoupling relativistic fluid at local thermodynamic equilibrium
Xin-Li Sheng, Francesco Becattini, Daniele Roselli
We present an upgraded formula for Wigner function and spin polarization of fermions emitted by a relativistic fluid at local thermodynamic equilibrium at the decoupling which impr…

Dissipative corrections to the particle momentum spectrum of a decoupling fluid
Francesco Becattini, Daniele Roselli, Xin-Li Sheng
We present an \emph{ab initio} calculation within quantum statistical field theory and linear response theory, of the dissipative correction to the momentum spectrum of scalar part…
