The quadratic growth of Krylov spread complexity in the BTZ black hole

Aranya Bhattacharya, Mario Flory, Michal P. Heller +2

The boundary quantity that captures the growth of black-hole interiors quantified by holographic complexity remains unknown beyond 2d dilaton gravity. We provide a critical analysi…

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…

De Sitter holographic complexity from Krylov complexity in DSSYK

Michal P. Heller, Fabio Ori, Jacopo Papalini +2

We utilize the recent connection between the high energy limit of the double-scaled SYK model and two-dimensional de Sitter solutions of sine dilaton gravity to identify the length…

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…

Far from equilibrium hydrodynamics of nonthermal fixed points

Jürgen Berges, Gabriel S. Denicol, Michal P. Heller +1

Nonthermal fixed points are paradigmatic far-from-equilibrium phenomena of relevance to high-energy physics, cosmology, and cold atomic gases. We propose that, despite their intrin…

Quantum complexity in gravity, quantum field theory, and quantum information science

Stefano Baiguera, Vijay Balasubramanian, Pawel Caputa +4

Quantum complexity quantifies the difficulty of preparing a state or implementing a unitary transformation with limited resources. Applications range from quantum computation to co…

Quasinormal modes of nonthermal fixed points

Matisse De Lescluze, Michal P. Heller

Quasinormal modes play a prominent role in relaxation of diverse physical systems to equilibria, ranging from astrophysical black holes to tiny droplets of quark-gluon plasma at RH…

Krylov spread complexity as holographic complexity beyond JT gravity

Michal P. Heller, Jacopo Papalini, Tim Schuhmann

One of the important open problems in quantum black hole physics is a dual interpretation of holographic complexity proposals. To date the only quantitative match is the equality b…

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…

Spacetime as a quantum circuit

A. Ramesh Chandra, Jan de Boer, Mario Flory +3

We propose that finite cutoff regions of holographic spacetimes represent quantum circuits that map between boundary states at different times and Wilsonian cutoffs, and that the c…
