The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

For this purpose, this new ion crystal clock was compared with other optical clocks and a new accuracy record was achieved. The PTB researchers report their in Physical Review Letters. An undisturbed ...

The new multi-ion design is scalable and its scalability is set to make the comparison short. If you have 10 ions in the clock, the measurement is 10 times faster. This is already an important ...

Our collection of antimatter has just gotten heavier, as researchers have logged the heaviest antimatter version of an atomic nucleus yet, called antihyperhydrogen-4.

Compared to atomic ions, these molecular ions have a more complex internal structure, as they contain two nuclei instead of one.Even when they are in their lowest possible electronic energy level ...
