TL;DR: In this article, the authors report the achievement of fusion fuel gains exceeding unity on the US National Ignition Facility using a high-foot implosion method, which is a manipulation of the laser pulse shape in a way that reduces instability in the implosion.

TL;DR: It is shown that, to first order in time, the dynamics are inertial, and constraints on the shape and curvature of the transition-state potential energy surface are placed, pointing toward analogies between this nonequilibrium phase transition and the short-time dynamics intrinsic to equilibrium liquids.

TL;DR: The comparison with radiation-hydrodynamic modeling indicates that low mode asymmetries and increased ablator surface perturbations may be responsible for the current performance of deuterium-tritium inertial confinement fusion implosion experiments.
