Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur—but ...

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 ...

Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

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 ...

Physicists at the MIT-Harvard Center for Ultracold Atoms have pulled off a feat once confined to the blackboards of theorists: they’ve taken the first direct images of atoms freely interacting in ...

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 ...

Atoms of the soft, silvery metal indium have been chilled to temperatures so cold that the particles can demonstrate strange quantum behaviour, such as forming new types of matter. Because indium ...

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 ...
