This work provides a framework for determining the buckling kinetics of membranes under compressive stress. The authors investigate a model of graphene with molecular dynamics simulations and find three regimes: I. Buckling time increases with temperature, II. Buckling time decreases with temperature, and III. Buckling time is independent of temperature.

In 2022, a National Ignition Facility controlled-fusion experiment reached a target gain , with the fusion energy produced exceeding the amount of laser energy required to drive the target. This result was obtained thanks to careful design described in this paper. This design has been shown to be robust and allows a better understanding of the physical conditions necessary to reach ignition.

The target gain greater than unity achieved in a recent fusion experiment was made possible by using additional laser energy at fixed power and controlling sources of degradation. This resulted in increased compression of the fuel and a high fusion yield corresponding to a novel physical regime. This paper describes the experimental evidence for these critical aspects and new observables.

This work describes Richtmyer-Meshkov experiments to measure the strain-rate sensitivity of copper in the high-rate regime. The authors extend the maximum strain rate by more than two orders of magnitude. At higher strain rates, their strength estimates show a steep increase that agrees well with extrapolations from some of the data in the literature. The work contributes to the important effort to understand how impacts can affect the strength of solids.
