Fig. 1. Schematic of the model and relevant parameters.

Fig. 2. Effective temperature of molecules as a function of optomechanical coupling constants (notice that all parameters are considered similar to the main paper, i.e., κ2π=33  THz, ωm2π=32.2  THz, g/2π=70  GHz, λ=0.2  THz, ΩPu2=0.22  eV2, δ=0, and we also ignore the probe laser Ωpr=0 because it is weak and far detuned from plasmonic cavity center frequency and hence does not play a role in heat transferring).

Fig. 3. Comparison between different methods (equipartition theorem, numerical, and corrected formula) for minimal measurable force as a function of molecular frequency, with two different effective temperatures.
