a Power spectral density amplification M = PSD(ω, δ)/PSD(ω, 0) as a function of the high-frequency drive. Parameters for the solid blue line are : σ = 0.0016, η = 0.001, α = 0.4, ω = 2π/200,000, F = 1.05 × 10−4 and γ = 0.15. The parameters for the dashed blue line are the same except F = 8.5 × 10−5 and γ = 0.05 (lower resonant and low-frequency drivings). b Evolution of the power spectral density magnification as function of the forcing (F) and the detuning (δ) for b γ = 0.15 and c γ = 0.05. White dashed vertical lines represent the cut at drivings used in a.
