Structural transitions in one-dimensionally confined one-component plasmas.
Layered structures occurring in strongly coupled one-dimensionally confined one-component plasmas are studied by means of Monte Carlo simulations. A series of structural transitions with alternating square and hexagonal symmetry is observed with increasing the width of the system. For closer interlayer separation, the square type of lattice (bcc in [100] or [110] plane) is dominating, whereas for wider separations the hexagonal (fcc in [111] plane or hcp) patterns are observed.
