Wigner Lattices and Born Melting
Prof. David Weitz
Harvard University
Location: MoSE G011

Wigner lattices are nearly defect-free, and they are formed through repulsive interactions exclusively. The absence of defects inhibits melting, making the crystal much more stable, and it reduces the energy difference between crystal and liquid. Thus, the melting transition acquires a distinct second-order character, even though it is strictly a first-order transition. This form of melting was first proposed by the German physicist Max Born nearly 80 years ago. It is only now that its study can be carried out. Reception to follow the Lecture
