    Researchers Comb Atoms into a Novel Swirl

    March 3, 2021

    When you brush your hair in the morning, there’s a pretty good chance you’re not thinking about quantum physics. But the way your hair swirls as you brush is actually related to some features of the quantum world. Important properties of quantum particles are described by topology—a field of mathematics that classifies objects according to how many holes they have. This is not merely a question of fashion. In physical materials, topology can determine many interesting properties. Now, a team of JQI researchers has engineered a new kind of topological matter—one with a single whorl—by breaking free from the constraints of crystalline solids. They managed to do this by grooming their atomic states into a whorl situated in an abstract, infinite plane, rather than a coconut or donut shape.

  • PRA Highlights Work of JQI Fellow during 50th Anniversary Celebration

    October 19, 2020

    A paper coauthored by JQI Fellow Ian Spielman in 2011 has been highlighted by the journal Physical Review A as part of its 50th anniversary celebration—one of only 26 that the journal plans to highlight in its “anniversary milestones” collection. The collection comprises papers published in the journal “that have made important contributions to atomic, molecular, and optical physics and quantum information by announcing significant discoveries or by initiating new areas of research.” Highlighting these notable papers is part of the American Physical Society’s celebration of the splitting of the journal Physical Review into four journals, Physical Review A-D, that each cover different specialized physics content.
