  • Laser Fusion Achieved at NIF

    Scientists at the National Ignition Facility (NIF) in Livermore, CA report that for the first time a laser-initiated plasma has produced more energy than was put into it.  Although the total amount of energy in the laser pulse was greater than that released, this is considered to be a significant step as greater than unity gain was achieved for the light that actually struck the target.  The group published their findings in Nature, the International Weekly Journal of Science.  News outlets, including NPR, have reported the story.

    A JILA team at Boulder, CO headed by Jun Ye has published their results on a new Strontium-based atomic clock demonstrating accuracy on the order of 1 second for the lifetime of the earth.  The clock, as reported in Nature1, has an accuracy of 6.4×10-18 and is based on a lattice of Strontium atoms.  The clock surpasses the accuracy of the previous record holders, clocks based on single ions2,3,4.

    Though the results were only released as an advanced online publication on 22 January (three days ago at the publication of this post), the clock has already been reported on in the mainstream media, including NPR, Nature World News, and the Daily Mail, demonstrating a widespread interest in atomic physics.

    Congratulations to the group for their efforts and results.

  • 2013 Nobel Prize in Physics Awarded to François Englert and Peter W. Higgs

    The 2013 Nobel Prize in Physics was awarded jointly to François Englert and Peter W. Higgs “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”
