摘要：

The longitudinal viscosity eta(l) is obtained for a two-dimensional (2D) liquid using a Green-Kubo method with a molecular dynamics simulation. The interparticle potential used has the Debye-Huckel or Yukawa form, which models a 2D dusty plasma. The longitudinal eta(l) and shear eta(s) viscosities are found to have values that match very closely, with only negligible differences for the entire range of temperatures that is considered. For a 2D Yukawa liquid, the bulk viscosity eta(b) is determined to be either negligibly small or not a meaningful transport coefficient. DOI: 10.1103/PhysRevE.87.013106
