The HERCULES laser has recently reached record intensities, as high as 10 22 W/cm 2 [1]. Such ultrahigh intensities create exciting opportunities for experiments in the ultra-relativistic and radiation dominated [2] regime of lasermatter interactions. Laser contrast, defined as the ratio of the peak intensity of the pulse to the prepulse intensity, must be at least 11 orders of magnitude to res...

[1] A growing multispectral database plus recent Galileo descent measurements are being used to construct a self-consistent picture of the Jupiter thermosphere/ionosphere system. The proper characterization of Jupiter’s upper atmosphere, embedded ionosphere, and auroral features requires the examination of underlying processes, including the feedbacks of energetics, neutral-ion dynamics, compos...

We report the first experimental demonstration of compensating Joule losses in metallic photonic metamaterial using optically pumped PbS semiconductor quantum dots.

Writing information onto nanoscale magnetic oscillators as magnetic bits presents many challenges, some of which become more formidable as we pursue higherdensity information storage. It is true that the electric current densities needed at present to rotate the magnetization direction are lower than those needed in traditional semiconductor devices, where information has to be constantly rewri...
