Abstract

We present non-equilibrium molecular dynamics simulation studies on the dynamic (complex) shear viscosity of a 2D many-particle system interacting via a Yukawa (Debye-Hückel) type inter-particle potential. Our investigations reveal the complex interplay of dissipative and elastic processes, as well as the effect of single particle resonances and enhanced collective excitations, and the influence of the external forces on the structural correlations in the system (© 2011 WILEY-VCH Verlag GmbH & Co.
