Controlled diffusion processes in an adiabatic model of a bouncing ball

This study explores the integration of a diffusion control parameter into the chaotic dynamics of a modified bouncing ball model. By extending beyond simple elastic collisions, the model introduces elements that affect the diffusive behavior of kinetic energy, offering insights into the interplay between deterministic chaos and stochastic diffusion. The research reinterprets the bouncing ball's interactions with the surface as short-distance collisions that mimic random thermal fluctuations of particles. This refined model reveals complex dynamics, highlighting the synergistic effects between chaos and diffusion in shaping the evolution of the system.

Normal and anomalous diffusion in a bouncing ball over an irregular surface

The problem of a bouncing ball on a non-planar surface is investigated. We discovered that surface undulation adds a horizontal component to the impact force, which acquires a random character. Some aspects of Brownian motion are found in the horizontal distribution of the particle. On the x-axis, normal and super diffusion are observed. For the probability density's functional form, a scaling hypothesis is presented.
