HOUSTON For the first time, a mixed gas of the two fundamental types of atoms has been cooled to a state of simultaneous quantum degeneracy-a state of matter in which atoms behave like ...

This press release is also available in German. There are two fundamentally distinct families of particles in nature: bosons and fermions. Being a boson or a fermion has profound consequences on the ...

Bosons and fermions, the two classes into which all particles--from the sub-atomic to atoms themselves--can be sorted, behave very differently under most circumstances. While identical bosons like to ...

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 ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Until now, atoms have never been imaged interacting freely in space, but a new technique known as ...

In the quantum world, the universe plays by rules so strange that even its smallest building blocks often defy intuition. Now, a team of physicists from Rice University and Max Planck suggests ...

MIT physicists have taken the first-ever direct images of individual atoms interacting freely in space. Their findings, published in the journal Physical Review Letters, reveal hidden quantum ...

If we want to see quantum weirdness with our eyes, we’ll need Bose-Einstein Condensates. The weird rules of quantum mechanics lead to all sorts of bizarre phenomena on tiny scales— particles ...

When a one-dimensional gas of strongly interacting bosons expands, the velocity distribution of the bosons transforms into one that is identical to non-interacting fermions. Bosons and fermions, the ...
