UW Professor Emeritus David J. Thouless wins Nobel Prize in physics for exploring exotic states of matter
The Royal Swedish Academy of Sciences announced Tuesday that David James Thouless, professor emeritus at the University of Washington, will share the 2016 Nobel Prize in physics with two of his colleagues. Thouless splits the prize with Professor F. Duncan M. Haldane of Princeton University and Professor J. Michael Kosterlitz of Brown University “for theoretical discoveries of topological phase transitions and topological phases of matter,” according to the prize announcement from the Academy. Half the prize goes to Thouless while Haldane and Kosterlitz divide the remaining half. Thouless is the UW’s seventh Nobel laureate, and second in physics after Hans Dehmelt in 1989.

UW researchers unleash graphene ‘tiger’ for more efficient optoelectronics
In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber’s energy gap, transferring just a small portion of light energy into electricity. The remaining energy is lost as heat. But in a paper released May 13 in Science Advances, Wu, UW associate professor Xiaodong Xu and colleagues at four other institutions describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.

Cooled down and charged up, a giant magnet is ready for its new mission
The Fermi National Accelerator Laboratory — or Fermilab — announced that a 680-ton superconducting magnet is secure in its new home and nearly ready for a new era of discovery in particle physics. This achievement follows the delicate, 3,200-mile transport of the magnet’s 17-ton, 50-foot-wide housing ring to the U.S. Department of Energy facility outside Chicago two years ago. The fully assembled magnet will drive high-energy particle experiments as part of an international partnership among 34 institutions, of which the University of Washington is a leading contributor.
