    "abstract": "A numerical model for a 2D-monolayer plasma crystal was established using the\nBox_tree code. Box_tree is a Barnes_Hut tree code which has proven effective in\nmodeling systems composed of large numbers of particles. Thermally excited\nwaves in this plasma crystal were numerically simulated and dispersion\nrelations for both the longitudinal and transverse wave modes were found. These\nwere compared with the dispersion relations extrapolated from experiment as\nwell as a theory based on harmonic approximation. The results were found to\nagree with theoretical dispersion relations under different wave propagation\ndirections with different particle charges and over a range of 0.9\u003ck\u003c5.",
