The matter family has added a new member. Most everyone knows the four most common forms of matter solid, liquid, gas, and plasma. A fifth, the Bose-Einstein condensate (BEC) was first observed in ...

Ultracold gases of fermionic atoms offer researchers a way to study quantum many-body phenomena using measurement techniques from atomic and molecular physics. In a new experiment, Hauke Biss of the ...

A long-sought new form of matter has been created for the first time. The matter, called a fermionic condensate, consists of atoms that are ordinarily forbidden to exist in the same quantum state but ...

Over the past 20 years, many physicists have studied ultra-cold fermionic systems contained in magnetic or optical traps. When an external magnetic field is applied to a two-species fermionic system, ...

Researchers have observed the spectrum of an ultracold atomic gas that can exist as a superfluid or a Bose-Einstein condensate in a study that could provide clues to the nature of superconductivity.
