Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena.

Small clouds of strontium atoms (blue) and rubidium atoms (red) are trapped together. The well-known properties of rubidium can be used to calibrate the applied magnetic field very precisely, which in ...

Talk about the perils of atomic radiation has swelled in volume and intensity ever since the U.S. and Russia fired their much-publicized H-bombs in 1954. From public forums and presses all over the ...
