Boost-invariant superfluid flows
Journal of High Energy Physics, 2022 We present some exact solutions to the ideal hydrodynamics of a relativistic superfluid with an almost-conformal equation of state. The solutions have stress tensors which are invariant under Lorentz boosts in one direction, and represent superfluid ...

New, Spherical Solutions of Non-Relativistic, Dissipative Hydrodynamics
Entropy, 2022 We present a new family of exact solutions of dissipative fireball hydrodynamics for arbitrary bulk and shear viscosities. The main property of these solutions is a spherically symmetric, Hubble flow field. The motivation of this paper is mostly academic:

Three-point functions from a Schwinger-Keldysh effective action, resummed in derivatives
Journal of High Energy PhysicsThe search for the conjectured QCD critical point in heavy-ion collisions requires to account for far-from equilibrium effects as well as fluctuations, and in particular non-Gaussian fluctuations, in the modeling of the dynamics of the hot and dense ...

Hydrodynamics as cospans of field theories into the BF theory
Hydrodynamics is based on conservation laws of currents: one starts from the conserved currents of the theory describing the microscopic dynamics, and provides an alternative parameterisation of these currents in terms of hydrodynamic variables (density, pressure, velocity, etc.).

Suppression of hyperuniformity in hydrodynamic scalar active field theories
Journal of Physics: Condensed MatterAbstract The coarsening dynamics at late times in phase-separating systems lead to universally hyperuniform patterns. This is well known for scalar field theories, such as the Cahn–Hilliard equation, but has also been shown for dry scalar active field theories.

A hydrodynamic approach to non-equilibrium conformal field theories [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2016 We develop a hydrodynamic approach to non-equilibrium conformal field theory. We study non-equilibrium steady states in the context of one-dimensional conformal field theory perturbed by the $T\bar T$ irrelevant operator. By direct quantum computation, we show, to first order in the coupling, that a relativistic hydrodynamic emerges, which is a simple ...

Causal and stable superfluid hydrodynamics
Journal of High Energy PhysicsWe investigate the linearized stability and causality properties of relativistic viscous superfluid hydrodynamics. The Landau-Lifshitz-Clark-Putterman formulation for the theory of relativistic viscous superfluids suffers from the same instability and ...

Diffusion coefficient matrix for multiple conserved charges: a Kubo approach
Journal of High Energy PhysicsThe strongly interacting matter created in relativistic heavy-ion collisions possesses several conserved quantum numbers, such as baryon number, strangeness, and electric charge.

Hydrodynamic theory of electron transport in a strong magnetic field [PDF]
Journal of Statistical Physics, 1987 The mode coupling contribution to the transverse transport coefficients of a three-dimensional one-component plasma in a strong external magnetic field is calculated. For very strong fields it is found that the tagged particle diffusion rate, the thermal diffusion rate, and the coefficient of viscosity in the plane orthogonal to the field have a Bohm ...
