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…
On the efficacy of virtual seminars
Hugo Camargo, Michal P. Heller, Ro Jefferson +4
During the SARS-CoV-2 pandemic, theoretical high-energy physics, and likely also the majority of other disciplines, are seeing a surge of virtual seminars as a primary means for sc…
Hydrodynamic attractors in phase space
Michal P. Heller, Ro Jefferson, Michał Spaliński +1
Hydrodynamic attractors have recently gained prominence in the context of early stages of ultra-relativistic heavy-ion collisions at the RHIC and LHC. We critically examine the exi…
