The research aims to explore the effects of hydrodynamic fluctuations and damped oscillatory friction on particle motion in complex environments.
Applied the fractional Langevin equation for particle motion analysis.
Modeled the friction force as a damped oscillating function using the Mittag-Leffler function.
Derived analytical solutions for various relaxation functions.
Identified explicit forms for position and velocity autocorrelation functions.
Demonstrated that particle motion becomes superdiffusive under specific time scales.
Established that hydrodynamic fluctuations and frictional forces create a memory effect exceeding the diffusional time scale.
