Going into the experiment, the researchers predicted that if the iron and helium were to fuse, they would find helium atoms worked into the crystal structure (known as a lattice) of iron.

Everyone's excited about a compound formed with helium, one of the periodic table's most inert elements. But this work has been under scrutiny for three years, and not everyone's convinced.

“Our calculations also revealed a dynamically stable crystal structure, supporting our experimental findings.” Altogether, this combination of experiments and calculations showed that the reaction ...

Magnetic helium makes superfluid time crystal Researchers observe time crystal and quasicrystal, throw in supersolid for fun.

Researchers from Japan and Taiwan reveal for the first time that helium, usually considered chemically inert, can bond with iron under high pressures. They used a laser-heated diamond anvil cell ...

Frozen helium prepared in a laboratory has apparently transformed into a superfluid solid, or supersolid—a never-before-seen phase of matter that theorists predicted more than 30 years ago.

At very low temperatures, helium can be solid and a perfect liquid at the same time. Theoreticians, though, have incorrectly explained the phenomenon for a long time. Computer simulations have now ...

Crystal structure of Na₂He, which resembles a 3D checkerboard. The purple spheres represent sodium atoms, which are inside the green cubes that represent helium atoms.
