“…Our results are important for strongly correlated two-component charged particle systems in general [1] and for complex plasmas in particular [6,7]. Common to all these systems are collective phenomena resulting in a rich variety of phases.…”

We investigate exciton bound-state formation and crystallization effects in two-dimensional electron-hole bilayers. Performing unbiased path integral Monte Carlo simulations all quantum and Coulomb correlation effects are treated on first principles. We analyze diverse pair distribution functions in dependence on the layer separation, particle density and hole-to-electron mass ratio and derive a schematic phase diagram for the neutral mass-asymmetric bilayer system. Our simulations reveal a great variety of possible phases namely an exciton gas, an exciton crystal, an electron-hole liquid and a hole crystal embedded in an electron gas.

“…In this work, we go further into this field by concentrating on Ag–Cu cluster growth on thin polymer films during sputter deposition. The sputter deposition technique is a well‐established and widely used method, but as a specific application of complex plasmas it is still in the focus of basic research . Sputtering allows high deposition rates and, in contrast to many wet chemical methods, the alloy composition and filling factor can be varied over a broad range , .…”

We present molecular dynamics (MD) simulation results for the growth of silver–copper nanoparticles on a polymeric surface during sputter deposition. The simulation procedure extends a previous implementation for gold nanoparticles to bimetallic nanoparticles. Making use of an accelerated version of MD, the timescales of the simulations become comparable to those of an actual deposition process, which may take several minutes in experiments. While silver and copper are known to be immiscible in the bulk, we trace the concentration profiles of Ag and Cu atoms in the clusters for film thicknesses up to 1.8 nm and are thus able to investigate the early stages of phase separation on the nanoscale.

The formation of wake fields downstream of an objects in flowing plasmas has strong implications on structure, stability and dynamics of complex plasmas. This paper aims at putting recent experimental investigations and different theoretical approaches on charging of dust grains, stability of dust grain arrangements and the dynamical properties of complex plasmas into perspective. Further, the combination of wake fields and grain confinement is discussed, which is the generic situation in complex plasmas. It is shown that in spherical traps the resulting competition of trap geometry and vertical alignment leads to a sophisticated mixture of nested shell and string order.
