Abstract

We analyze the dissipation of the frequency vibrations of nano-mechanical devices. We show that the coupling between flexural modes and two-level systems leads to sub-ohmic dissipation. The inverse quality factor of the low energy vibrations depends on temperature as Q^-1 (T) ≈ Q_0 + C T^1/3, providing a quantitative description of the experimental data.
