abstract
Using numerical holography, we study the collision of a planar sheet of energy with a bounded localized distribution of energy. The collision, which mimics proton-nucleus collisions, produces a localized lump of debris with transverse size $R \sim 1/T_{\rm eff}$ with $T_{\rm eff}$ the effective temperature, and has large gradients and large transverse flow. Nevertheless, the postcollision evolution is well described by viscous hydrodynamics. Our results bolster the notion that debris produced in proton-nucleus collisions may be modeled using hydrodynamics.

Attractors Without Scaling: Adiabatic Hydrodynamization With and Without Inelastic Scattering
Including inelastic scattering in a simplified gluon kinetic theory speeds up hydrodynamization, and attractors appear through gapped eigenstates of an effective Hamiltonian even without pre-thermal scaling.

Attractodynamics in 0+1D
Attractodynamics constructs a macroscopic closure around a nonthermal attractor; in the 0+1D BSY kinetic model, ideal and viscous truncations track the full kinetic evolution, with the viscous extension improving agre...
