Morphing between particle and wave characteristics of a CNT mechanical phonon. Phonon occupation a n₁ and b n₂ as a function of the relative phase ϕ and the rotation angle φ. The analytical results (colored surfaces) are in excellent agreement with the numerical simulations (black symbols). Here, in addition to γ_s/2π = 200γ_m/2π = 80 Hz, we assume that g/2π = 100 kHz, ω_m/2π = 2 MHz, Ω = 10ω_m, and Δ₋ = 142ω_m, resulting in ω_q ≃ 1.5ω_m and then J/2π ≃ × 12 kHz, and that n_th = 100, corresponding to an environmental temperature of ≃10 mK
