(Phys.org) —In an atom laser, millions of individual atoms propagate through space with minimal spreading, just like photons propagate in a coherent photon laser beam. Although both types of lasers are similar, atom lasers ...
(Phys.org) —The physics behind some of nature's spectacular sights have been observed at very low temperatures - less than a thousandth of a degree away from absolute zero - by a collaboration of researchers from the University ...
