Pseudo-gauge invariant non-equilibrium density operator
F. Becattini, C. Hoyos
We obtain a form of the local thermodynamic equilibrium density operator which is invariant under pseudo-gauge transformations of the stress-energy and the spin tensors. This opera…
On the local thermodynamic relations in relativistic spin hydrodynamics
Francesco Becattini, Rajeev Singh
We demonstrate, by providing two specific examples, that the local differential thermodynamic relations used as educated guesses in relativistic hydrodynamics with spin, do not hol…
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…
Dissipative currents and transport coefficients in relativistic spin hydrodynamics
Asaad Daher, Xin-Li Sheng, David Wagner +1
We determine the form of dissipative currents at the first order in relativistic spin hydrodynamics with finite chemical potential including gradients of the spin potential. Taking…
Vector and Tensor Spin Polarization for Vector Bosons at Local Equilibrium
Zhong-Hua Zhang, Xu-Guang Huang, Francesco Becattini +1
We derive expressions for the vector and tensor components of the spin polarization of massive vector bosons at local thermodynamic equilibrium up to second order in the space-time…
