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…
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…
