Video of a Wigner crystal (VIDEO) Princeton University This video is under embargo. Please login to access this 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).
