]]>A minimal coarse-grained model for $T=1$ viral capsids assembled from 20 protein rigid trimers has been designed by extending a previously proposed form of the interaction energy written as a sum of anisotropic pairwise interactions between the trimeric capsomers. The extension of the model has been p…

]]>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.

]]>In 2022, a National Ignition Facility controlled-fusion experiment reached a target gain $G>1$, 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.
