The structure factor ($\mathcal{S}_{nn}\,(k,\omega)$) of dynamical density fluctuation is studied in the presence of the out-of-equilibrium modes ($\phi$) within the scope of relativistic viscous hydrodynamics. The $\mathcal{S}_{nn}\,(k,\omega)$ without the $\phi$ modes shows three peaks of Lorentzian types, identified as one Rayleigh peak and two Brillouin peaks, symmetrically situated about...

Heavy ion collisions that aim to probe phase transitions and critical phenomena require robust predictions. In order to scan the QCD phase diagram and gain insight into the exact nature of these transitions and the conjectured critical point, numerical simulations are increasingly used.
Mapping a system onto a finite lattice, with discrete spatial steps, effectively cuts off the theory in...

18. Adiabatic hydrodynamization in the bottom-up thermalization scenario

In this talk we demonstrate that the early stages of the bottom-up thermalization scenario [1] are well described by the adiabatic hydrodynamization framework. All of the qualitative features exhibited in QCD effective kinetic theory (EKT) simulations at weak coupling [2] are captured by the emergence of an effective low-energy instantaneous ground state for the 1-particle gluon distribution...
