Time-Periodic Solutions of Driven-Damped Trimer Granular Crystals

Figure 5

Same as Figure 3 but for a driving frequency of  kHz, which lies in the first spectral gap. (a) Profile of solution for a driving amplitude of  μm. (b) The bifurcation diagram for  kHz (shown here) is similar to the one presented in Figure 3(b), which was for a driving frequency in the second gap ( kHz). However, the bifurcation points occur for much larger values of the driving amplitude and the structure of the solutions themselves varies considerably in comparison to the second gap (see text). (c) Zoomed out version of panel (b). In this case, the jump of the experimental data is likely due to driving out of a controllable range (see text), rather than to chaos, as in the case of the second gap breathers.
