Atomic clocks are established as the most precise timekeepers created. Atomic clocks work by deploying lasers to measure the vibrations of atoms (electromagnetic signals). By atoms oscillating at a ...

Researchers at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) have introduced a technique, Tune-IMS, designed to improve the precision of isochronous mass spectrometry (IMS) in measuring short ...

An international team of physicists has successfully measured the size of a certain type of neutrino to a certain degree. In their paper published in the journal Nature, the group describes ...

(Nanowerk News) Scanning transmission electron microscopy (STEM) allows us to visualize the position of individual atoms inside materials and calculate atomic displacements. However, its precision is ...

A study on the quantum processes titled "Time-reversal-based quantum metrology with many-body entangled states" has been published in the journal Nature Physics. Researchers from the Massachusetts ...

Tests of relativity once required accurate clocks separated by thousands of kilometres. Optical techniques have now made such tests possible in an atomic cluster measuring no more than one millimetre ...

For centuries, time was tied to Earth’s rotation, with a second defined as a fraction of a full day. But inconsistencies in the planet’s spin made that system unreliable for scientific use. Since 1967 ...

Researchers at the University of Illinois at Chicago describe a new technique for precisely measuring the temperature and behavior of new two-dimensional materials that will allow engineers to design ...

Physicists have measured Albert Einstein's theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...
