Abstract
Collective excitations in a two-dimensional fluid with repulsive dipole-like interactions are systematically studied by molecular dynamics simulations. A two-oscillator model is used to reconstruct dispersion curves and to measure q-gap boundary values in the dispersion relation of the transverse (shear) mode. Functional form for the dependence of the q-gap boundary value on the coupling parameter is suggested. The results obtained can be used in future investigations of collective excitations in fluids, especially in two-dimensional cases.
