我们展示了各向异性粒子的反平移运动如何受到连续自发局部化模型（CSL）的影响，CSL是薛定谔方程最突出的假设修正，在宏观尺度上恢复实在性。我们推导了描述坍缩诱导的空间定向退相干的主方程，并演示了它如何导致线性和角动量扩散。由于相关的加热速率随CSL参数的变化而变化，因此后者可以通过测量单个悬浮纳米转子的随机运动来单独确定。
We show how the ro-translational motion of anisotropic particles is affected by the model of continuous spontaneous localization (CSL), the most prominent hypothetical modification of the Schrodinger equation restoring realism on the macroscale. We derive the master equation describing collapse-induced spatio-orientational decoherence and demonstrate how it leads to linear- and angular-momentum diffusion. Since the associated heating rates scale differently with the CSL parameters, the latter can be determined individually by measuring the random motion of a single levitated nanorotor.
