Relativistic second-order dissipative hydrodynamics from Zubarev's non-equilibrium statistical operator
Arus Harutyunyan, Armen Sedrakian, Dirk H. Rischke
We present a new derivation of relativistic second-order dissipative hydrodynamics for quantum systems using Zubarev's non-equilibrium statistical-operator formalism. This is achie…
Numerical fluid dynamics for FRG flow equations: Zero-dimensional QFTs as numerical test cases. I. The model
Adrian Koenigstein, Martin J. Steil, Nicolas Wink +4
The functional renormalization group (FRG) approach is a powerful tool for studies of a large variety of systems, ranging from statistical physics over the theory of the strong int…
Spectral representation of the shear viscosity for local scalar QFTs at finite temperature
Peter Lowdon, Ralf-Arno Tripolt, Jan M. Pawlowski +1
In local scalar quantum field theories (QFTs) at finite temperature correlation functions are known to satisfy certain non-perturbative constraints, which for two-point functions i…
From Kadanoff--Baym to Boltzmann equations for massive spin-1/2 fermions
Xin-Li Sheng, Nora Weickgenannt, Enrico Speranza +2
We derive Boltzmann equations for massive spin-1/2 fermions with local and nonlocal collision terms from the Kadanoff--Baym equation in the Schwinger--Keldysh formalism, properly a…
Derivation of the nonlocal collision term in the relativistic Boltzmann equation for massive spin-1/2 particles from quantum field theory
Nora Weickgenannt, Enrico Speranza, Xin-li Sheng +2
We derive the Boltzmann equation and the collision kernel for massive spin-1/2 particles, using the Wigner-function formalism and employing an expansion in powers of . The p…
Relativistic quantum fluid with boost invariance
D. Rindori, L. Tinti, F. Becattini +1
We study a relativistic fluid with longitudinal boost invariance in a quantum-statistical framework as an example of a solvable non-equilibrium problem. For the free quantum field,…
