Temperature ratio as a function of the normalized interparticle distance for the crystal-liquid phase separation curve in Ref. 27 and (bold curve) and (thin curve).
Normalized DAW velocity vs following from Eq. (15) for low and : (thin curve) and (bold curve). Dotted line corresponds to the ordinary DAW solution (Ref. 1).
Dependence of DAW velocity upon the Havnes parameter following from Eq. (15) for low and fixed : (thin curve) and (bold cuvre). Dotted line indicates the standard DAW solution (Ref. 1).
Example of dimensionless dispersion relation (15): normalized frequency vs normalized wave number in a strongly coupled regime. The parameter values are relevant for the wave experiments in microgravity conditions of Ref. 19: , , and (bold curve). The standard DAW dispersion law is indicated by dotted lines.
Comparison between the experimentally measured fluctuation spectrum of the DAW intensity (reproduced from Fig. 2a of Ref. 15) and the theoretical dispersion relation (12) for two values of the particle charge number (lower solid curve) and (upper solid curve). The regular DAW solution corresponding to is shown by dotted curves. Dispersion relation (12), which incorporates the effect of strong interactions between dust grains, provides an excellent agreement with experiment.
