Abstract

In a recent paper [Wang, Huang, and Feng, Phys. Rev. E 99, 063206 (2019)], Langevin dynamical simulation results related to the shear modulus G of a two-dimensional liquid dusty plasma were reported. The purpose of this Comment is to provide a comparison with available theoretical models to calculate G and to indicate the correct way of interpreting the numerical results.
