“Nonergodicity of Confined Superdiffusive Fractional Brownian Motion: Ensemble vs Time-Averaged Measurements”

https://pubmed.ncbi.nlm.nih.gov/38115422

This study investigates the nonergodicity of confined superdiffusive fractional Brownian motion and finds a significant difference between ensemble- and time-averaged measurements for Hurst exponents greater than 1/2, with a wide range of individual time-averaged displacements as the exponent approaches 1.
