Lightwave electronics at sharp metal tips

(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics control for the first time the emission of electrons from metal tips with femtosecond lasers alone.

Metamaterials provide active control of 'slow light' devices

LANL researchers and collaborators have made the first demonstration of rapidly switching on and off "slow light" in specially designed metamate­rials at room temperature. Metamaterials are assemblies of multiple individual ...

Watching electrons in molecules

(PhysOrg.com) -- A research group led by ETH Zurich has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry ...

High-resolution, terahertz-driven atom probe tomography

Materials scientists must be able to exert ultrafast control of matter using a strong electromagnetic field on the atomic scale to understand the ionization dynamics and excitations in solids. Researchers can couple picosecond ...

Recreating conditions inside stars with compact lasers

The energy density contained in the center of a star is higher than we can imagine - many billions of atmospheres, compared with the 1 atmosphere of pressure we live with here on Earth's surface.
