First atom laser shoots pulses of coherent matter

Article Abstract:

A team led by Wolfgang Ketterle at MIT has put the Bose-Einstein condensate, an exotic state of matter first accomplished in 1995, to use in a pulsed beam of atoms that behaves like laser light. Applications for coherent atomic pulses could range from atomic clocks to the semiconductor industry.

Researchers build a novel laser by putting a lock on atoms

Article Abstract:

Researchers in Boulder, CO, and Houston, TX, have developed the first lasers that work without population inversion, in which more atoms in the lasing medium have to be in the excited state than in the ground state. A quantum interference blocks atoms in the ground state from absorbing photons.

Has CERN made the stuff of the newborn universe?

Article Abstract:

Researchers at CERN report indications that they have recreated quark-gluon plasma in their Super Proton Synchrotron particle accelerator. The evidence involves the disapperance of J/psi particles in lead-lead collisions.
