Characterization of two-dimensional elliptical complex plasma

An elliptical complex plasma is a system of $n$ particles with the same charge $q$ and mass $m$ confined in a two-dimensional anisotropic well. Particles interact through a screened Coulomb potential with a Debye length $\lambda$. An elliptical complex plasma has been created experimentally using a rectangular aperture (17.5~mm $\times$ 30.2~mm) placed on a flat electrode to create an anisotropic parabolic well. Measured properties of this system will be compared with computed configurations and normal modes.
