Quasi-hydrodynamics beyond the conventional paradigm
Lorenzo Gavassino
Quasi-hydrodynamics extends hydrodynamics by promoting slowly relaxing variables to additional degrees of freedom. For such a framework to be rigorously defined and parametrically…
Exact resummation of hydrodynamics for arbitrary elastic scattering integral
Lorenzo Gavassino
We consider monoenergetic particles propagating in three spatial dimensions and undergoing elastic scattering off an external medium. For an arbitrary rotationally invariant scatte…
Thermal boundaries for relativistic fluids without a conserved charge
Lorenzo Gavassino, Soeren Schlichting, Gabriel S. Denicol
We study an ultrarelativistic fluid with no conserved particle number in a planar slab geometry bounded by two parallel, thermally conducting plates held at fixed (possibly differe…
Effective field theory of quasi-hydrodynamics from kinetic theory
Lorenzo Gavassino
Quasi-hydrodynamics describes systems with quasi-conserved degrees of freedom, namely observables that relax on timescales that are finite but parametrically longer than microscopi…
Relativistic transport near moving interfaces
Lorenzo Gavassino
We study linear disturbances localized near planar surfaces moving at constant velocity in relativistic media. Depending on the physical setting, the surface may represent a mo…
The Lorentzian geometry of relaxation
Lorenzo Gavassino
We show that relativistic theories with purely relaxational excitation spectra, such as kinetic theory and transient hydrodynamics, naturally endow the dispersion plane …
The quasi-normal modes of relativistic Fokker-Planck kinetic theory
Lorenzo Gavassino
Employing the well-known unitary equivalence between Fokker-Planck operators and Schrödinger Hamiltonians, we compute the quasi-normal-mode spectrum of ultrarelativistic kinetic th…
The diffusion equation is compatible with special relativity
Lorenzo Gavassino
Due to its parabolic character, the diffusion equation exhibits instantaneous spatial spreading, and becomes unstable when Lorentz-boosted. According to the conventional interpreta…
How Lorentz boosts reshape relaxation spectra
Lorenzo Gavassino
In relativity, relaxation processes are often assumed to undergo time dilation under Lorentz boosts. We show that this intuition fails generically. Due to relativity of simultaneit…
Relativistic superfluid profiles near critical surfaces
Lorenzo Gavassino, Alexander Soloviev
Landau's two-fluid model of superfluidity ceases to apply in regions where the condensate amplitude exhibits rapid spatial variation, such as vortex cores or in the vicinity of con…
Stationary Couette-type flows in relativistic fluids
Lorenzo Gavassino, Patrick Niekamp, Sören Schlichting +1
We investigate a class of stationary, planar-symmetric solutions of relativistic hydrodynamics, in which a dissipative fluid is confined between two parallel plates that move relat…
Thermoelectric Conduction in General Relativity: A Causal, Stable, and Well Posed Theory
Lorenzo Gavassino
We present a covariantly stable first-order framework for describing charge and heat transport in isotropic rigid media embedded in curved spacetime. Working in the Lorenz gauge, w…
Heat propagation in rotating relativistic bodies
Lorenzo Gavassino, Marco Antonelli
We investigate heat propagation in rigidly rotating bodies within the theory of general relativity. Using a first-order gradient expansion, we derive a universal partial differenti…
Spontaneous charge separation in accelerating relativistic plasmas
Lorenzo Gavassino
The Stewart-Tolman effect posits that accelerating conductors exhibit both charge separation and rest-frame electric fields (``inertia of charge''), while the Ehrenfest-Tolman effe…
Dispersion relations of relativistic radiation hydrodynamics
Lorenzo Gavassino
We compute the linearised dispersion relations of shear waves, heat waves, and sound waves in relativistic ''matter+radiation'' fluids with grey absorption opacities. This is done…
On the importance of geometry in exoplanet irradiation : Implications for the day-night contrast
Mradumay Sadh, Lorenzo Gavassino
The irradiance received by a spherical body or a planet close to a spherically symmetric source does not follow the point-sized source approximation and the inverse-square variatio…
Relativistic heat conduction in the large-flux regime
Lorenzo Gavassino
We propose a general procedure for evaluating, directly from microphysics, the constitutive relations of heat-conducting fluids in regimes of large fluxes of heat. Our choice of hy…
Mapping GENERIC hydrodynamics into Carter's multifluid theory
Lorenzo Gavassino
We show that the GENERIC model for relativistic heat conduction is a multifluid of Carter. This allows one to compute the multifluid constitutive relations directly from the GENERI…
