Intense, femtosecond laser pulse focused on a nano structured, ordered ‘pillar’ target, exciting beams of ultrashort electron pulses at MeV energies. Highlights the role of such structured surfaces ...

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new ...

Images of relativistic electrons trapped in graphene quantum dots have been taken by physicists in the US and Japan. The ability to confine and control electrons in such a way could play an important ...
