Abstract
Through Monte Carlo simulations of rapidly quenched one-component plasmas, we investigate microscopically the dynamic evolutions of local and extended bond-orientational symmetries in supercooled states and show that the resulting states are the Coulomb glasses. The glass states are characterized by random polycrystalline structures with long-range bond-orientational order; in these states the particles are virtually locked around their equilibrium positions. The inverse temperature at the glass transition is found between 200 and 300 in units of the average Coulomb energy. The polycrystalline structures of the resulting glasses depend sensitively on how the rapid quench is applied. Physical problems specific to the Coulombic systems are discussed.
