Remarkably, the atoms were able to cross this barrier collectively and without energy loss, behaving as if the barrier were transparent, thanks to quantum tunneling. As the oscillating current flowed ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

Produced inside NASA’s Cold Atom Lab, the bubbles provide new opportunities to experiment with an exotic state of matter. Since the days of NASA’s Apollo program, astronauts have documented (and ...

Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is causing such excitement. Instead of slowing down when particles collide, this ...

Scientists have used ultracold atoms to successfully demonstrate a novel method of particle acceleration that could unlock a new understanding of how cosmic rays behave, a new study reveals. Subscribe ...

Extremely cold atoms have been used to measure gravity more precisely than we thought possible, beating a limit that stems from quantum weirdness. Ultracold atoms are some of the most sensitive force ...

An artist’s illustration of a quantum fluid made from atoms (gold), streaming along a wall made from laser light (green), and effortlessly navigating around obstacles placed in their path. Typically, ...

For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms. In this experiment, an alternating current was applied to a Josephson ...
