We evaluate the full opacity dependence of collective flow in high-energy heavy-ion collisions within a microscopic kinetic description based on the Boltzmann equation in the conformal relaxation time approximation. By comparing kinetic theory calculations to hydrodynamic and hybrid simulations for an average initial state, we point out shortcomings and inaccuracies of hydrodynamic models and present modified simulation setups to improve them.

Imaging non-hydrodynamic modes with jet wakes
In the long-wavelength limit, jet-wake angular moments with ℓ≥3 vanish in hydrodynamics and directly image the non-hydrodynamic relaxation spectrum of the medium.

Collective dynamics in heavy and light-ion collisions -- II) Determining the origin of collective behavior in high-energy collisions
A new observable, W, built from ratios of flow cumulants and transverse energies in same-nucleus collisions at RHIC and LHC, is proposed and validated as a measure of how close a collision system is to hydrodynamic behavior.

Experimentally accessible drive-induced attractor in a Fermi gas near unitarity
A rapid scattering-length sweep in a near-unitary Fermi gas produces an early-time attractor that is visible only in the joint (E, Π) state space, not in a single-variable curve.

Collective dynamics in heavy and light-ion collisions -- I) Kinetic Theory vs. Hydrodynamics
Event-by-event simulations show elliptic flow in heavy and light ion collisions follows a universal opacity-dependent response curve; hydrodynamics is accurate only above opacity around 3, and oxygen collisions expose...
