“The whole history of the universe can be understood as a sequence of condensations,” says Charles Lineweaver, a physicist at the Australian National University. Each new class of fundamental ...

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 a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

Adding energy to a group of ultracold atoms should make them fly away from each other with many different energies, but ...

Researchers have demonstrated that by using argon plasma, metal atoms can be dispersed and guided to desired positions. This new strategy ensures that not a single atom goes to waste and maximizes ...

Instead of choreography, physicists speak of vibrational modes. While the motion patterns of molecules with two or three atoms are fairly easy to follow, it quickly becomes complex with medium ...
