Evidence of Macroscopic Quantum Tunneling Detected in Nanowires

Wednesday, May 27, 2009 - 16:28 in Physics & Chemistry

A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.
