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 ...

Are quantum particles polygamous? New experiments suggest some of them abandon long-standing partnerships when ...

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 ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

"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 ...

All atoms are either fermions or bosons depending on whether they possess half-integer or integer spin, and the difference between the two becomes clear when they are cooled to near absolute zero.

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 ...

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 ...

Condensed matter physicists have come a step closer to their dream laboratory, with the news that two independent teams have managed to trap bosons and fermions together in a 3D optical lattice. The ...

If I roll a pair of dice and you get to bet on one number, what do you choose? The smart choice is 7 because there are more ways for 2 dice to come up 7 than any other number. Well, it turns out that ...
