A one-way street for spinning atoms
Work correlating ultracold atoms’ spin with their direction of motion may help physicists model new circuit devices and unusual phases of matter.
Single-photon transmitter could enable new quantum devices
Long-sought goal for quantum devices — the ability to transmit single photons while blocking multiple photons — is finally achieved.
Watching a gas turn superfluid
New work on ultracold gases may also help scientists understand high-temperature superconductors and neutron stars.
The bouncing gas
Clouds of gases that bounce off each other could help physicists model the behavior of high-temperature superconductors and other unusual materials.
