And also perhaps here: Note that they used lasers to REMOVE energy from the system (to COOL it). That's what KP Sinha did, and also, what Ed Storms was unaware of here on Vortex-L until I pointed it out.

The scientific team headed by Hanns-Christoph Nägerl has published a paper about quantum phase transitions in a one dimensional quantum lattice in the scientific journal Nature.* With a Bose-Einstein condensate of cesium atoms, scientists at the Institute for Experimental Physics of the University of Innsbruck have created one dimensional structures in an optical lattice of laser light. In these quantum lattices or wires the single atoms are aligned next to each other with laser light preventing them from breaking ranks On Fri, Mar 14, 2014 at 11:13 PM, Kevin O'Malley <kevmol...@gmail.com>wrote: > Also perhaps here, this smart guy: > > *A.
