JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested "Fermi sea," thus keeping atoms in a high-energy state, or excited, for about 10% longer than usual by delaying their normal ...

A team of researchers affiliated with several institutions in Germany and two in France has set a new record for the lowest temperature ever recorded in a lab setting—38 picokelvins. In their paper published in the journal ...
Physicists at EPFL have found a way to get photons to interact with pairs of atoms for the first time. The breakthrough is important for the field of cavity quantum electrodynamics (QED), a cutting-edge field leading the ...
