CALET succeeds in direct measurements of cosmic-ray electron spectrum up to 4.8 TeV

more »
Researchers have succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET). Observations by CALET are expected to reveal the mysteries of cosmic-rays and nature of dark matter in the future.

Puzzling results explained: A multiband approach to Coulomb drag and indirect excitons

more »
A new theoretical study explains previous mystifying experimental results, in which coupled charged particles moved in exactly the opposite direction to that predicted. This apparently contradictory phenomenon is associated with the bandgap in dual-layer graphene structures, a bandgap which is very much smaller than in conventional semiconductors.
