Its properties can be probed on Earth using ultra-cold atoms. Photo credit: PSU DURHAM, N.C. - Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. The measurements verify that this gas can be used as a "scale model" of exotic matter, such as super-high temperature superconductors, the nuclear matter of neutron stars, and even the state of matter created microseconds after the Big Bang. The results may also allow experimental tests of string theory in the future. Duke physicist John Thomas made the viscosity measurements using an ultra-cold Fermi gas of lithium-6 atoms trapped in a millimeter-sized bowl made of laser light. The team's report appears in the Dec. 10 issue of Science.
