Abstract
After a brief introduction to lattice gases, the power spectral density of density fluctuations is computed in the general case. It is then shown that conditions can be found to represent acoustic relaxation. Next, transverse excitations are studied and it is shown that it is possible to obtain either purely relaxing or propagating shear waves. Taking intermediate conditions leads to viscoelastic behaviour.
