    "abstract": "Thermally excited waves in a Plasma crystal were numerically simulated using\na Box_Tree code. The code is a Barnes_Hut tree code proven effective in\nmodeling systems composed of large numbers of particles. Interaction between\nindividual particles was assumed to conform to a Yukawa potential. Particle\ncharge, mass, density, Debye length and output data intervals are all\nadjustable parameters in the code. Employing a Fourier transform on the output\ndata, dispersion relations for both longitudinal and transverse wave modes were\ndetermined. These were compared with the dispersion relations obtained from\nexperiment as well as a theory based on a harmonic approximation to the\npotential. They were found to agree over a range of 0.9\u003ck\u003c5, where k is the\nshielding parameter, defined by the ratio between interparticle distance a and\ndust Debye length lD. This is an improvement over experimental data as current\nexperiments can only verify the theory up to k = 1.5.",
