Molecular dynamics simulations have been employed to investigate the phase transition phenomena in three-dimensional strongly coupled Yukawa systems (SC-YSs) under the influence of an external uniaxial AC electric field (MT). Lattice correlation function (LCF) and radial distribution function (RDF) tests are used to investigate the phase transitions in SC-YSs with and without electric fields. The states of dust grains depend on plasma coupling (Γ), screening length (κ) and MT strength. In the absence of MT, the new calculations of LCF and RDF demonstrate the self-organization of dust grains with increasing Γ and decreasing κ. Furthermore, condensation (gas–liquid) and solidification (liquid–crystal) transitions are observed in SC-YSs with increased MT intensities and Γ values. Moreover, gas-like states of the YS require significantly higher MT intensity, while liquid-like or near solid-like states require intermediate to low MT intensity, respectively, to achieve solidification. It is illustrated that the SC-YSs exhibit electrorheological behavior that is the same as conventional electrorheological fluids. Due to these characteristics, the SC-YSs can be used to investigate the electrorheological properties of condensed and soft matter physics.
