Real space circuit complexity as a probe of phase diagrams
Nishan C. Jayarama, Viktor Svensson
Circuit complexity has been used as a tool to study various properties in condensed matter systems, in particular as a way to probe the phase diagram. However, compared with measur…
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…
Exponential Approach to the Hydrodynamic Attractor in Yang-Mills Kinetic Theory
Xiaojian Du, Michal P. Heller, Sören Schlichting +1
We use principal component analysis to study the hydrodynamic attractor in Yang-Mills kinetic theory undergoing the Bjorken expansion with Color Glass Condensate initial conditions…
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…
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…
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.…
How does relativistic kinetic theory remember about initial conditions?
Michal P. Heller, Viktor Svensson
Understanding hydrodynamization in microscopic models of heavy-ion collisions has been an important topic in current research. Many lessons obtained within the strongly-coupled (ho…
Hydrodynamization in kinetic theory: Transient modes and the gradient expansion
Michal P. Heller, Aleksi Kurkela, Michal Spalinski +1
We explore the transition to hydrodynamics in a weakly-coupled model of quark-gluon plasma given by kinetic theory in the relaxation time approximation with conformal symmetry. We…
