The New Phase of Matter
A new phase of matter has been discovered seventy years after Albert
Einstein predicted it's existence. In this new state of matter, atoms do not move around
like they would in an ordinary gas condensate. The atoms move in lock step with one
another and have identical quantum properties. This will make it easier for physicists to
research the mysterious properties of quantum mechanics. It was named "Molecule of
the Year" because it was such a major discovery, but it is not a molecule at all. The
phase, called the Bose-Einstein condensate (BEC) follows the laws of quantum physics.
In early 1995, scientists at the National Institute of Standards and
Technology and the University of Colorado were the first to uncover the BEC. They
magnetically trapped rubidium atoms and then supercooled the atoms to almost absolute
zero. The graphic on the cover shows the Bose-Einstien condensation, where the atom's
velocities peak at close to zero velocity, and the atoms slowly emerge from the
condensate. The atoms were slowed to the low velocity by using laser beams. The hardware
needed to create the BEC is a bargain at $50,000 to $1000,000 which makes it accessible to
physics labs around the world.
The next step is to test the new phase of matter. We do not know yet if
it absorbs, reflects,or refracts light. BEC is related to superconductivity and may unlock
some mysteries of why some minerals are able to conduct electricity without resistance.
The asymmetrical pattern of BEC is is thought by some astrophysicists to explain the bumpy
distribution of matter in the early universe, a distribution that eventually led to the
formation of galaxies. Physicists are working on creating an atom laser, using new
technology derived from the BEC. The new lasers would be able to create etchings finer
than those that etch silicon chips today.
The discovery of BEC has prompted a lot of research of the new phase.
BEC is expected to yield benefits to industry and society. I expect that large businesses
will take advantage of the new technology and start making products using the technology.
This will probably be in the form of the atom lasers BEC is expected to make possible. The
lasers might be used for laser surgery, or any application where lasers are used today.
