چکیده

We show that dipole-dipole interactions induced by gravitational force and possibly ion-stream drag force give rise to stable triangular and oriented cubic crystalline structures recently observed in a dusty plasma, as opposed to only unoriented cubic close-packed structures usually expected of Wigner crystals. In certain cases the dipole interaction may flatten the crystal significantly. We calculate the phase diagrams of the crystals and analyze and explain some of their features. @S1063-651X~97!09305-7#

Phase diagram of crystals of dusty plasma

Dust particles effectively charged by plasma recently have been optically observed to exhibit crystalline phases not expected of Wigner or Yukawa crystals. Under varying conditions the crystal sometimes appears as deformed and oriented three-dimensional close-packed lattices of bcc, fcc, or hcp type, but mostly as a triangular array of vertical chains of particles. The unusual phases are shown ...

Phase Diagram of Strongly Coupled Yukawa Particulates in Deformable Background and Application to Fine Particle (Dusty) Plasmas

We analyze thermodynamics of the system composed of charged particles with hard cores interacting via the repulsive Yukawa potential and the ambient plasma (of ions and electrons), taking the contribution of the latter properly into account. When the Coulomb coupling between particles becomes sufficiently strong, the isothermal compressibility of the whole system diverges and we have a phase se...

Reentrant transitions in colloidal or dusty plasma bilayers.

The phase diagram of crystalline bilayers of particles interacting via a Yukawa potential is calculated for arbitrary screening lengths and particle densities. Staggered rectangular, square, rhombic, and triangular structures are found to be stable including a first-order transition between two different rhombic structures. For varied screening length at fixed density, one of these rhombic phas...

Charge gradient effects on modulated dust lattice wave packets in dusty plasma crystals

  Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...

Investigation of Dust-Ion Acoustic Waves in a Magnetized Collisional Dusty Plasma with Kappa Distribution Function for Electrons

The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...
