Abstract
Anomalous diffusion, the deviation of particle spreading from Brownian motion, is common in soft matter and biology. This paper introduces a robust criterion for identifying anomalous diffusion using power spectral analysis of single trajectories. The criterion's robustness is tested against measurement errors and validated with various experimental data exhibiting both normal and anomalous diffusion.
