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…
