abstract
We show how to generate non-trivial solutions to the conformally invariant, relativistic fluid dynamic equations by appealing to the Weyl covariance of the stress tensor. We use this technique to show that a recently studied solution of the relativistic conformally invariant Navier-Stokes equations in four-dimensional Minkowski space can be recast as a static flow in three-dimensional de Sitter space times a line. The simplicity of the de Sitter form of the flow enables us to consider several generalizations of it, including flows in other spacetime dimensions, second order viscous corrections, and linearized perturbations. We also construct the anti-de Sitter dual of the original four-dimensional flow. Finally, we discuss possible applications to nuclear physics.

A unified exact boost-invariant solution of the relativistic Boltzmann equation is derived for flat, spherical, and hyperbolic foliations of dS3 x R, yielding the new Grozdanov flow on the hyperbolic slicing.
Out-of-equilibrium superfluids in Bjorken, Gubser and FLRW flows reach hydrodynamic attractors after an initial-condition-dependent attractor time, with a novel nonlinear constant-anisotropy regime in Gubser evolution.
Analytic nonlinear response coefficients for v2 and v4 in Gubser flow are derived, including a participant-plane angle factor that modifies strength and sign of the response.
Carroll hydrodynamics with spin is obtained as the c→0 limit of relativistic hydrodynamics with spin, extending the description of boost-invariant flows.
Energy-energy correlators in heavy-ion collisions exhibit classical hydrodynamic scaling from collective flow at large angles within the small-angle regime, collective modes at smaller angles, and light-ray OPE at even smaller angles.
Models chemical non-equilibrium in finite-density QGP under conformal Gubser flow and its impact on hard thermal photon production, finding delayed equilibration with quarks lagging gluons, suppressed total yield but enhanced early high-pT photons, and distinct temporal emission structure.
