Kovtun, Son and Starinets proposed a bound on the shear viscosity of any fluid in terms of its entropy density. We argue that this bound is always saturated for gauge theories at large 't Hooft coupling, which admit holographically dual supergravity description.

  1. A Critical Point on the Hairy Black Hole Phase Boundary in the Improved Holographic Einstein-Maxwell-Dilaton Theory

    hep-th 2025-09 conditional novelty 5.0 of 10

    In the improved holographic EMD model, two hairy black hole phases are separated by a U-shaped boundary whose lower branch is first-order and upper branch third-order, meeting at (mu_B,T)=(765.51,86.54) MeV.

  2. Scaling functions in the soft-wall AdS/QCD models

    hep-ph 2025-07 conditional novelty 5.0 of 10

    Soft-wall AdS/QCD models reproduce mean-field chiral scaling functions and follow a T_c scaling law whose slope, tuned by a modified potential, can approach Dyson-Schwinger results.

  3. Dynamics of chiral phase transition in a $N_f=2+1$ soft-wall AdS/QCD model

    hep-ph 2025-07 conditional novelty 4.0 of 10

    In a 2+1 flavor soft-wall AdS/QCD model, the chiral condensate exhibits slow, non-trivial relaxation with a metastable plateau or overshoot when quenched close to the phase transition.
