Hydrodynamic attractors
Tilman Enss, Michal P. Heller, Alexandre Serantes +1
Attractors are effective low-dimensional structures, defined in a chosen set of observables, that trajectories from different initial states approach; hydrodynamic attractors are t…
Temporal Entanglement from Twist Correlators in 2d Conformal Field Theory and Holography
Alice Bernamonti, Federico Galli, Michal P. Heller +2
We formulate timelike entanglement entropy and its Rényi extension in two-dimensional conformal field theory through the analytic continuation of replica twist correlators to time-…
Stable evolution of relativistic hydrodynamics order-by-order in gradients
Michal P. Heller, Alexandre Serantes, Michał Spaliński +1
We provide a systematic framework for solving the initial value problem for relativistic hydrodynamics formulated as a gradient expansion. Secular growth is handled by a suitable c…
Temporal Entanglement from Holographic Entanglement Entropy
Michal P. Heller, Fabio Ori, Alexandre Serantes
Recently, several notions of entanglement in time have emerged as a novel frontier in quantum many-body physics, quantum field theory and gravity. We propose a systematic prescript…
Multitrace deformations and the nonlinear stability of Anti-de Sitter space
Alexandre Serantes, David Travieso Mayo, Javier Mas
We investigate the nonlinear stability of global Anti-de Sitter space in the presence of multitrace deformations utilizing an Einstein-Klein-Gordon system with a top-down scalar po…
Geometric Interpretation of Timelike Entanglement Entropy
Michal P. Heller, Fabio Ori, Alexandre Serantes
Analytic continuations of holographic entanglement entropy in which the boundary subregion extends along a timelike direction have brought a promise of a novel, time-centric probe…
The Hydrohedron: Bootstrapping Relativistic Hydrodynamics
Michal P. Heller, Alexandre Serantes, Michał Spaliński +1
As an effective theory, relativistic hydrodynamics is fixed by symmetries up to a set of transport coefficients. A lot of effort has been devoted to explicit calculations of these…
Rigorous bounds on transport from causality
Michal P. Heller, Alexandre Serantes, Michał Spaliński +1
We use causality to derive a number of simple and universal constraints on dispersion relations, which describe the location of singularities of retarded two-point functions in rel…
Convergence of the Fefferman-Graham expansion and complex black hole anatomy
Alexandre Serantes, Benjamin Withers
Given a set of sources and one-point function data for a Lorentzian holographic QFT, does the Fefferman-Graham expansion converge? If it does, what sets the radius of convergence,…
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…
Gravitational wave driving of a gapped holographic system
Anxo Biasi, Javier Mas, Alexandre Serantes
This work addresses the response of a holographic conformal field theory to a homogeneous gravitational periodic driving. The dual geometry is the AdS-soliton, which models a stron…

We construct a family of very simple stationary solutions to gravity coupled to a massless scalar field in global AdS. They involve a constantly rising source for the scalar field…

Raúl Arias, Javier Mas, Alexandre Serantes
We study linear and nonlinear stability of asymptotically AdS solutions in Einstein-Maxwell-scalar theory. After summarizing the set of static solutions we first examine thermo…
Holographic Quenches with a Gap
Emilia da Silva, Esperanza Lopez, Javier Mas +1
In order to holographically model quenches with a gapped final hamiltonian, we consider a gravity-scalar theory in anti-de Sitter space with an infrared hard wall. We allow a time…

Javier Mas, Alexandre Serantes
We study the dynamics of a spherically symmetric thin shell of perfect fluid embedded in d-dimensional Anti-de Sitter space-time. In global coordinates, besides collapsing solution…
Collapse and Revival in Holographic Quenches
Emilia da Silva, Esperanza Lopez, Javier Mas +1
We study holographic models related to global quantum quenches in finite size systems. The holographic set up describes naturally a CFT, which we consider on a circle and a sphere.…
