Video of a Wigner crystal (VIDEO) Princeton University This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption The video describes melting processes of an electron Wigner crystal into electron liquid phases. As the electron density (\nu, a measure of number of electrons in a magnetic field, is controlled by applying electric voltages) is increased, more electrons (dark blue sites) enter the field of view, and a periodic structure of a triangular lattice emerges. The periodic structure is first melted (near \nu = 0.334) where the map shows homogeneous signals. And then it reappears at higher density \nu, and eventually melts again (\nu = 0.414).
