Magnetism Observed In Gas For The First Time Sep 18, 2009
Since the number of constituents is odd, lithium-6 is a fermion a class of exotic particles that have a half-integral spin and has properties similar to an electron ... For decades, scientists have debated whether it is in principle possible for a gas or liquid of fermions, which are not in a periodic crystal, to become ferromagnetic ... If confirmed, the MIT result may enter the textbooks on magnetism, showing that a gas of fermions does not need a crystalline structure to be ferromagnetic. (Science Daily)
Physicists Discover Important Step For Making Light Crystals Apr 13, 2009
The researchers are trying to trap atomic particles called fermions, which have an internal angular momentum called spin. When fermions are hot, they spin chaotically ... Ho and Zhou discovered that by raising the laser intensity, researchers could compress the fermions into a so-called band insulator, where each cell in the lattice contains two fermions instead of one.

Ultracold Gas Mimics Ultrahot Plasma Mar 7, 2009
Thomas reported on his laboratory's experiments with "fermion" gases and their possible relevance to RHIC's "quark-gluon plasma" research as well as to string theory during a Feb. 15 symposium organized by Brookhaven during the American Association of Science's 2009 Annual meeting, held in Chicago ... Lithium atoms are of the fermion class, meaning that that their spin-states normally make them keep more of a distance from each other than their chummier counterpart class of atoms -- the bosons...
