标题： Explaining Optomechanical Libration Spectra: A Stochastic Simulation Approach

摘要： 我们提出了一种实用且计算有效的伊藤-泰勒展开式基于的随机模拟框架，用于建模旋转光机械实验。 通过使用该框架建立模型，我们可以捕捉到光学悬浮的几乎圆柱对称纳米哑铃的非线性取向动力学。 它成功地再现并解释了在摆动功率谱密度中观察到的肩部特征，我们证明这些特征来源于受限摆动与粒子对称轴热驱动旋转之间的相互作用。 显示英文摘要

摘要： 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.
