As a particle moves through a fluid, it may generate a laminar wake behind it. In the gauge-string duality, we show that such a diffusion wake is created by a heavy quark moving through a thermal plasma and that it has a universal strength when compared to the total drag force exerted on the quark by the plasma. The universality extends over all asymptotically anti-de Sitter supergravity constructions with arbitrary scalar matter. We discuss how these results relate to the linearized hydrodynamic approximation and how they bear on our understanding of di-hadron correlators in heavy ion collisions.

  1. Visualizing How the Structure of Large-Radius Jets Shapes Their Wakes

    hep-ph 2025-01 conditional novelty 7.0 of 10

    Hybrid Model simulations show ATLAS large-radius jet data rule out fully coherent jet energy loss, and low-pT jet-shape observables can visualize merging subjet wakes.

  2. Energy-energy correlators inside single inclusive jets in heavy-ion collisions with CoLBT-hydro model

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    Updated CoLBT-hydro simulations with Q_M=2.0 GeV reproduce CMS in-jet EEC data, validate background subtraction, and show path-length and diffusion-wake effects.

  3. Rapidity asymmetry of jet-hadron correlation as a robust signal of diffusion wake induced by di-jets in high-energy heavy-ion collisions

    hep-ph 2025-01 conditional novelty 6.0 of 10

    Predicts that the rapidity asymmetry of jet-hadron correlations in di-jets with a rapidity gap is a background-free observable for the jet-induced diffusion wake.

  4. What is the Quark-Gluon Plasma made of?

    nucl-th 2025-06 accept novelty 2.0 of 10

    The quark-gluon plasma is best described as a strongly coupled liquid of massive, very short-lived quark and gluon quasiparticles, with sound (phonon) modes becoming the most well-defined collective excitation at low momenta.
