Nonequilibrium molecular-dynamics studies on the anisotropic viscosity of perfectly aligned nematic liquid crystals

The Miesowicz viscosities ${\mathrm{\eta }}_1$, ${\mathrm{\eta }}_2$, and ${\mathrm{\eta }}_3$ and the Leslie coefficients ${\gamma }_1$ and ${\gamma }_2$ of perfectly aligned nematics are determined by nonequilibrium molecular-dynamics simulations. The results are compared with theoretical predictions and with experimental data.
