Size of helium nucleus measured more precisely than ever before

In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever before. With the aid of the new value, ...

Adding or subtracting single quanta of sound

Researchers perform experiments that can add or subtract a single quantum of sound—with surprising results when applied to noisy sound fields.

Optimal information about the invisible

Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required—and this prerequisite is not always satisfied. In biomedicine, for ...

Scientists use diamonds to generate better accelerator beams

Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce ...

Optical computing at sub-picosecond speeds

Vanderbilt researchers have developed the next generation of ultrafast data transmission that may make it possible to make already high-performance computing "on demand." The technology unjams bottlenecks in data streams ...

Temporal control of light echoes

Scientists at Paderborn University, the Technical University of Dortmund and the University of Würzburg have for the first time used laser pulses to precisely control photon echoes, which can occur when light waves superimpose ...
