Relativity opens the door to a counterintuitive fact: A state can be stable to perturbations in
one frame of reference and unstable in another one. For this reason, the job of testing the …

It was recently shown that the dispersion relations describing singularities of retarded two-
point functions in causal quantum field theories always satisfy the fundamental inequality Im …

The stability conditions of a relativistic hydrodynamic theory can be derived directly from the
requirement that the entropy should be maximized in equilibrium. Here, we use a simple …

We have applied thermodynamic stability analysis to derive the stability and causality
conditions for conventional relativistic viscous hydrodynamics and spin hydrodynamics. We …

The faithful inclusion of the effects of bulk viscosity induced by the presence of chemical
reactions is an important issue for simulations of core-collapse supernovae, binary neutron …

We set up a general framework for systematically building and classifying, in the linear
regime, causal and stable dissipative hydrodynamic theories that, alongside with the usual …

Close to equilibrium, the kinetic coefficients of a thermodynamic system must satisfy a set of
symmetry conditions, which follow from the Onsager-Casimir principle. Here, we show that, if …

We study the GENERIC hydrodynamic theory for relativistic liquids formulated by Öttinger
and collaborators. We use the maximum entropy principle to derive its conditions for linear …

We provide rigorous criteria to determine whether the nonhydrodynamic sector of a
relativistic kinetic theory is gapless. These general criteria apply to both Boltzmann's …

We consider the evolution equations for the bulk viscous pressure, diffusion current, and
shear tensor derived within second-order relativistic dissipative hydrodynamics from kinetic …
