The field of complex (dusty) plasmas—low-temperature plasmas containing charged
microparticles—is reviewed: The major types of experimental complex plasmas are briefly …

It is common in mesoscopic systems to find instances where several charges interact among
themselves. These particles are usually confined by an external potential that shapes the …

We study the minimum energy equilibrium configurations of a classical two-dimensional
system of point charges confined by a triangular, square and disk region with a hard-wall …

Stable vortex states are studied in large superconducting thin disks (for numerical purposes
we considered disks with radius R= 50 ξ). Configurations containing more than 700 vortices …

Uniform triangular crystals are the ground state for particles that interact isotropically in two
dimensions. However, when immersed in an external potential, for example, one arising …

We study the ground state properties of classical Coulomb charges interacting with a 1∕ r
potential moving on a plane but confined either by a circular hard-wall boundary or by a …

Small quasi-two-dimensional dust clusters consisting of three to eleven particles are formed
in an argon plasma under varying rf power. Their normal modes are investigated through …

Topological defects are found in particles confined to planar disks interacting via the 1/r
Coulomb potential. The total interior topological charge is found to monotonically converge …

We develop the theory of the coupling between in-plane order and out-of-plane geometry in
twisted, two-dimensionally ordered filament bundles based on the nonlinear continuum …

We study a system of colloidal spheres with induced magnetic dipoles confined in two-
dimensional (2D) hard-wall channels using Brownian dynamics simulations. The external …
