Physics & Astronomy Seminar: “How trapping will set you free: What levitated ions can tell us about particle physics and magnetism”
Paul Hess, Visiting Assistant Professor, Middlebury College, will speak. Isolating, trapping, and levitating atomic or molecular ions in ultra-high vacuum environments provides a unique experimental tool to explore both fundamental and applied physics. In this talk, I will discuss my recent research using crystals of levitated atomic ions to study new and exotic types of magnetic matter. The properties of these tiny crystals, typically only 10 to 50 atoms long, are governed by the laws of quantum physics. Our trapped ion crystals can mimic types of magnetism unfamiliar from everyday life and serve as a toolbox for testing many-body quantum theory. I will also discuss plans for future research using the unique properties of molecular ions to expand the questions accessible in an ion trapping lab. The structure of such molecules presents new challenges in using them as tools in quantum simulation and measurement, but also new potential benefits. I will discuss ways my lab would use molecular ions to enhance experiments that simulate quantum magnetism and also as a system to study the properties of fundamental particles, like the shape of the electron.
