(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the ...

FRANKFURT. It was one of the biggest surprises in the history of science: In the early days of quantum physics around 100 years ago, scholars discovered that the particles which make up our matter ...

Japanese researchers have revealed how weak magnetic fields can instantly control the direction of electrical flow in quantum metals. Quantum metals are materials in which quantum effects, usually ...

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough ...

A technical paper titled “Measuring electrical properties in semiconductor devices by pixelated STEM and off-axis electron holography (or convergent beams vs. plane waves).” was published by ...

Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at ...

In a breakthrough discovery, scientists have unveiled a novel method for X-ray generation, offering enhanced flexibility in emitting X-rays in various directions or focusing them. A nurse checks the ...
