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…
