Primordial Weibel instability

Nahuel Miron-Granese et al.

Summary: In this study, we investigate the mechanism of amplification of primordial magnetic fields by studying the onset of vector instabilities in the post-inflationary epoch of the Universe. We consider the presence of a charged spectator scalar field during Inflation, and examine the effects of gravitational particle creation during the transition from Inflation to Reheating. We show that under certain conditions, the anisotropy and charge excess generated by the rapid transition can lead to a Weibel instability, which can compensate for the conformal dilution of the primordial magnetic field.

Thermodynamic Stability Implies Causality

L. Gavassino et al.

Summary: This paper investigates the relationship between the stability conditions of a relativistic hydrodynamic theory and the maximization of entropy in equilibrium. Using a simple geometrical argument, it is proven that in a stable theory, localized perturbations cannot propagate outside their future light cone. This implies that acausal theories in relativistic hydrodynamics must be thermodynamically unstable, at least near equilibrium. The study reveals a deep connection between stability and causality, which arises from the relationship between entropy and information.

Extended relaxation time approximation and relativistic dissipative hydrodynamics

Dipika Dash et al.

Summary: Development of a new framework for deriving order-by-order hydrodynamics from the Boltzmann equation is necessary to address the violations of conservation laws caused by the widely used Anderson-Witting formalism when relaxation-time depends on particle energy or in a hydrodynamic frame other than the Landau frame. In this study, we generalize an existing framework and extend the Anderson-Witting relaxation-time approximation to derive relativistic dissipative hydrodynamics consistently. The present framework is compatible with conservation laws and yields first-order hydrodynamic equations in the Landau frame. Additionally, corrections to the transport coefficients due to energy dependence of the relaxation-time are observed, indicating deviations from the Anderson-Witting approximation.

Transport coefficients of second-order relativistic fluid dynamics in the relaxation-time approximation

Victor E. Ambrus et al.

Summary: In this study, we calculate the transport coefficients of second-order fluid dynamics with 14 dynamical moments using the method of moments and the Chapman-Enskog method. Contrary to previous findings, our results show that the two methods yield identical second-order transport coefficients. Additionally, we address the divergence issue of diffusion-shear coupling coefficients in certain approximations and validate our results through numerical simulations.

Far-from-equilibrium kinetic dynamics of λ?4 theory in an expanding universe

Nicki Mullins et al.

Summary: We investigate the far-from-equilibrium behavior of the Boltzmann equation for a gas of massless scalar field particles with quartic self-interactions (lambda phi 4) in Friedmann-Lemaitre-Robertson-Walker spacetime. We analytically determine a subset of the spectrum and the corresponding eigenfunctions of the linearized Boltzmann collision operator using a new covariant generating function. Our results show that the cross section of lambda phi 4 decreases with energy, leading to direct coupling between moments of different orders. Numerical solutions for the scalar field case are provided and compared to those of a gas of hard spheres.

Numerical fluid dynamics for FRG flow equations: Zero-dimensional QFTs as numerical test cases. I. The O eth N THORN model

Adrian Koenigstein et al.

Summary: The functional renormalization group (FRG) approach is a powerful tool used in various fields to study different systems. This study introduces a novel method to solve flow equations using the analogy between RG equations and fluid dynamics. By applying this analogy to zero-dimensional quantum-field theoretical models, insights into RG flows and their interpretation, as well as the irreversibility of RG flows, can be gained. Additionally, numerical techniques developed in fluid dynamics can be applied to solve RG equations, allowing for the treatment of nonanalytic behavior in the RG flow.

Steady asymptotic equilibria in conformal relativistic fluids

Esteban Calzetta

Summary: The study focuses on the decay rate to equilibrium of a conformal fluid in kinetic theory under the relaxation time approximation, comparing it to two hydrodynamic schemes. The results show that accounting for the second moments of the distribution function is a significant improvement over the first model, which only considers the first moment.

Extended relaxation time approximation and relativistic dissipative hydrodynamics

Dipika Dash et al.

Summary: In this study, a new framework for deriving relativistic dissipative hydrodynamics from the Boltzmann equation with energy-dependent relaxation time is developed. The framework is shown to be compatible with conservation laws and corrections to transport coefficients due to energy dependence of relaxation time are discussed. The ratios of these transport coefficients are studied using a parametrized relaxation-time, revealing interesting scaling features.

Connecting far-from-equilibrium hydrodynamics to resummed transport coefficients and attractors

Gabriel S. Denicol et al.

Summary: Studies have shown the potential presence of hydrodynamic attractors in simulations of quark-gluon plasma formed in heavy ion collisions. Using Lagrangian schemes to solve relativistic viscous fluid equations is argued to be useful in characterizing these attractors. Preliminary results in Israel-Stewart theory support this claim, along with a discussion on performing slow-roll expansion in Israel-Stewart theory to define a resummed shear viscosity coefficient dependent on hydrodynamic field gradients.

Relativistic viscous effects on the primordial gravitational waves spectrum

Nahuel Miron-Granese

Summary: This study examines the impact of viscous effects of the primordial plasma on the evolution of the primordial gravitational waves (pGW) spectrum, using a second-order theory framework. Two main contributions are identified: the viscous evolution of pGW and the GW production due to initial spin-2 fluctuations of the fluid. The former effect is characterized by a relative amplitude decrease of about 1 to 10% compared to the GW free evolution spectrum.

Novel Relaxation Time Approximation to the Relativistic Boltzmann Equation

Gabriel S. Rocha et al.

Summary: The widely used relaxation time approximation to the relativistic Boltzmann equation has flaws when energy-dependent relaxation time or general matching conditions are considered. A new approximation is proposed to address these issues while maintaining basic properties of the linearized Boltzmann collision operator. The correction is shown to affect transport coefficients such as bulk viscosity and particle diffusion.

Linearized dispersion relations in viscous relativistic hydrodynamics

Guillermo Perna et al.

Summary: The dispersion relations for scalar, vector, and tensor modes of a viscous relativistic fluid were calculated and compared with results derived from kinetic theory and causal first-order theories. The study found that different methods show similar dynamics for scalar and vector modes, while the specific divergence-type theory presented contains propagating damped tensor waves. These conclusions support the application of hydrodynamics in problems involving the interaction between fluids and gravitational waves.

Fully developed relativistic turbulence

Esteban Calzetta

Summary: A simple model was used to study nonlinear phenomena in a real relativistic fluid, focusing on new types of behavior without nonrelativistic equivalents, such as an entropy cascade driven by fluctuations in the theory's tensor degrees of freedom. The von Karman-Howarth equations for this kind of turbulence were derived, along with considerations of correlations corresponding to fully developed turbulence.

Dissipative spin dynamics in relativistic matter

Samapan Bhadury et al.

Summary: This study extends the recent formulation of perfect-fluid hydrodynamics for spin-polarized fluids to include dissipation, using the classical description of spin degrees of freedom. The analysis is based on classical kinetic equations for massive particles with spin 1/2, treating collision terms in the relaxation time approximation. The kinetic-theory framework allows for the calculation of a complete set of new kinetic coefficients characterizing dissipative spin dynamics.
