"Experimental results we obtained on numerous reactions involving positively charged atoms or molecules revealed that some reactions still take place close to the absolute zero of the temperature ...

To physicists, temperature is a measure of how fast atoms are moving, a reflection of their energy—and absolute zero is the point at which there is absolutely no heat energy remaining to be ...

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

In the diagrams presented in the other three sections, the points show where atoms would lie if there were no motion due to heat; that is, if the metal's temperature were at absolute zero (-273°C).

Aquark’s quantum sensing technology could offer submarines precise navigation and the ability to map the seafloor like never ...

A suitcase-sized quantum sensor could soon reveal hidden water, oil, and even underground mountains—all by tracking how atoms ...

The cold-atom approach involves using finely focused laser beams (the ‘optical tweezers’) to trap individual atoms in a two-dimensional grid held at temperatures close to absolute zero.

Once the magnetic field is lowered, only the coldest and thus slowest atoms remain in the trap. With decreasing temperature, very close to absolute zero, the atoms behave like a single 'giant atom' – ...

A more precise definition of the second is crucial to all sorts of physical measurements – but to get there, scientists have ...
