Bounds on transport from univalence and pole-skipping
Sašo Grozdanov
Bounds on transport represent a way of understanding allowable regimes of quantum and classical dynamics. Numerous such bounds have been proposed, either for classes of theories or…
Coupling Constant Corrections in a Holographic Model of Heavy Ion Collisions with Nonzero Baryon Number Density
Åsmund Folkestad, Sašo Grozdanov, Krishna Rajagopal +1
Sufficiently energetic collisions of heavy ions result in the formation of a droplet of a strongly coupled liquid state of QCD matter known as quark-gluon plasma. By using gauge-gr…
The complex life of hydrodynamic modes
Sašo Grozdanov, Pavel K. Kovtun, Andrei O. Starinets +1
We study analytic properties of the dispersion relations in classical hydrodynamics by treating them as Puiseux series in complex momentum. The radii of convergence of the series a…
On the convergence of the gradient expansion in hydrodynamics
Sašo Grozdanov, Pavel K. Kovtun, Andrei O. Starinets +1
Hydrodynamic excitations corresponding to sound and shear modes in fluids are characterised by gapless dispersion relations. In the hydrodynamic gradient expansion, their frequenci…
Adding new branches to the "Christmas tree" of the quasinormal spectrum of black branes
Sašo Grozdanov, Andrei O. Starinets
In holography, quasinormal spectra of black branes coincide with the poles of retarded finite-temperature correlation functions of a dual quantum field theory in the limit of infin…
On the connection between hydrodynamics and quantum chaos in holographic theories with stringy corrections
Sašo Grozdanov
Pole-skipping is a recently discovered signature of many-body quantum chaos in collective energy dynamics. It establishes a precise connection between resummed, all-order hydrodyna…
