Magnetic Fields and Strong Correlations in One-Component Plasmas — •Torben Ott — Institut für Theoretische Physik und Astrophysik, Christian-Albrechts-Universität Kiel

The One-Component Plasma (OCP) is a paradigmatic model for a diverse number of plasmas, ranging from the interior of white dwarfs and neutron star crusts to laboratory dusty plasmas. The thermodynamic state of the OCP is fully characterized by a single parameter, the coupling parameter Γ∝ 1/T. For 1<Γ<175, the OCP is in a strongly correlated liquid state in which strong particle interactions modify the behaviour of the plasma and lead, e.g., to the existence of transverse (shear) waves.

The transport properties [1] and the wave spectra [2,3] of a strongly correlated liquid OCP in the presence of a strong magnetic field (i.e., ω_c/ω_p≈ 1) are relevant to both laboratory and astrophysical plasmas and reveal a number of surprising features. This talk gives a unifying overview of recent theoretical and simulational results for such magnetized OCPs.
