Initial state and approach to equilibrium
Michał Spaliński
A possible resolution of the early thermalisation puzzle is provided by the notion of far-from-equilibrium attractors which arise due to the specific kinematics of heavy-ion collis…
Relativistic Hydrodynamics: A Singulant Perspective
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
There is growing evidence that the hydrodynamic gradient expansion is factorially divergent. We advocate for using Dingle's singulants as a way to gain analytic control over its la…
Hydrodynamic Gradient Expansion Diverges beyond Bjorken Flow
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
The gradient expansion is the fundamental organising principle underlying relativistic hydrodynamics, yet understanding its convergence properties for general nonlinear flows has p…
Transient Relativistic Fluid Dynamics in a General Hydrodynamic Frame
Jorge Noronha, Michał Spaliński, Enrico Speranza
We propose a new theory of second-order viscous relativistic hydrodynamics which does not impose any frame conditions on the choice of the hydrodynamic variables. It differs from M…
Convergence of hydrodynamic modes: insights from kinetic theory and holography
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
We study the mechanisms setting the radius of convergence of hydrodynamic dispersion relations in kinetic theory in the relaxation time approximation. This introduces a qualitative…
Constraining the initial stages of ultrarelativistic nuclear collisions
Jakub Jankowski, Syo Kamata, Mauricio Martinez +1
It is frequently supposed that quark-gluon plasma created in heavy-ion collisions undergoes free streaming at early times. We examine this issue based on the assumption that a univ…
Transseries for causal diffusive systems
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
The large proper-time behaviour of expanding boost-invariant fluids has provided many crucial insights into quark-gluon plasma dynamics. Here we formulate and explore the late-time…
Hydrodynamic gradient expansion in linear response theory
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
A foundational question in relativistic fluid mechanics concerns the properties of the hydrodynamic gradient expansion at large orders. We establish the precise conditions under wh…
On the hydrodynamic attractor of Yang-Mills plasma
Michał Spaliński
There is mounting evidence suggesting that relativistic hydrodynamics becomes relevant for the physics of quark-gluon plasma as the result of nonhydrodynamic modes decaying to an a…
Gradient expansion for anisotropic hydrodynamics
Wojciech Florkowski, Radoslaw Ryblewski, Michał Spaliński
We compute the gradient expansion for anisotropic hydrodynamics. The results are compared with the corresponding expansion of the underlying kinetic-theory model with the collision…
Resurgence in Extended Hydrodynamics
Inês Aniceto, Michał Spaliński
It has recently been understood that the hydrodynamic series generated by the Müller-Israel-Stewart theory is divergent, and that this large order behaviour is consistent with the…
