DESCRIPTION:In 1934 Eugene Wigner first predicted that a gas of electrons 
 at zero temperature is susceptible to a quantum freezing transition when i
 ts density is made low enough\, due to the long-ranged Coulomb interaction
  between electrons. This Wigner crystal (WC) state has only very recently 
 been realized and visualized in two dimensional materials without applied 
 magnetic field. Here I discuss new forms of the Wigner crystal state that 
 can arise in materials with Berry curvature. I focus specifically on bilay
 er graphene\, and discuss the phase diagram and the different ordered stat
 es of the Wigner crystal.
