A quantum information perspective on meson melting
Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
We propose to use quantum information notions to characterize thermally induced melting of nonperturbative bound states at high temperatures. We apply tensor networks to investigat…
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…
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…
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…
From spin chains to real-time thermal field theory using tensor networks
Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
One of the most interesting directions in theoretical high-energy and condensed-matter physics is understanding dynamical properties of collective states of quantum field theories.…
