Stochastic fluctuations and the relaxation time in transient relativistic fluids
Gabriel S. Denicol, Jorge Noronha
We argue that the ratio between the shear viscosity and the shear relaxation time, , should be defined as a thermodynamic quantity obtained from the equal-time symmetric cor…
Branch-cut in the shear-stress response function of massless with Boltzmann statistics
Gabriel S. Rocha, Isabella Danhoni, Kevin Ingles +2
Using an analytical result for the eigensystem of the linearized collision term for a classical system of massless scalar particles with quartic self-interactions, we show that the…
Theories of Relativistic Dissipative Fluid Dynamics
Gabriel S. Rocha, David Wagner, Gabriel S. Denicol +2
Relativistic dissipative fluid dynamics finds widespread applications in high-energy nuclear physics and astrophysics. However, formulating a causal and stable theory of relativist…
Resummed hydrodynamic expansion for a plasma of particles interacting with fields
L. Tinti, G. Vujanovic, J. Noronha +1
A novel description of kinetic theory dynamics is proposed in terms of resummed moments that embed information of both hydrodynamic and non-hydrodynamic modes. The resulting expans…
A resummed method of moments for the relativistic hydrodynamic expansion
L Tinti, G Vujanovic, J Noronha +1
The relativistic method of moments is one of the most successful approaches to extract second order viscous hydrodynamics from a kinetic underlying background. The equations can be…
Nonlinear dynamics from the relativistic Boltzmann equation in the Friedmann-Lemaître-Robertson-Walker spacetime
D. Bazow, G. S. Denicol, U. Heinz +2
The dissipative dynamics of an expanding massless gas with constant cross section in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe is studied. The mathematic…
Exact solutions of the Boltzmann equation and optimized hydrodynamic approaches for relativistic heavy-ion collisions
U. Heinz, D. Bazow, G. S. Denicol +5
Several recent results are reported from work aiming to improve the quantitative precision of relativistic viscous fluid dynamics for relativistic heavy-ion collisions. The dense m…
Analytic solution of the Boltzmann equation in an expanding system
D. Bazow, G. S. Denicol, U. Heinz +2
For a massless gas with constant cross section in a homogeneous, isotropically expanding spacetime we reformulate the relativistic Boltzmann equation as a set of non-linear coupled…
Determination of the Shear Viscosity Relaxation Time at Weak and Strong Coupling
G. S. Denicol, J. Noronha, H. Niemi +1
We investigate the microscopic origin of the relaxation time coefficient in relativistic fluid dynamics. We show that the extraction of the shear viscosity relaxation time via the…
Microscopic Origin of the Shear Relaxation Time in Causal Dissipative Fluid Dynamics
G. S. Denicol, H. Niemi, J. Noronha +1
In this paper we show how to compute the shear relaxation time from an underlying microscopic theory. We prove that the shear relaxation time in Israel-Stewart-type theories is giv…
