| contents | We present a practical and computationally effective Ito-Taylor expansion based stochastic simulation framework for modeling rotational optomechanics experiments. By developing a model using this framework, we could capture the nonlinear orientation dynamics of an optically levitated, nearly cylindrically symmetric nanodumbbell. It successfully reproduces and explains shoulder-like features observed in the power spectral density of libration, which we show arising from the interplay between confined libration and thermally driven rotation around the particle symmetry axis. |
