Abstract: | We study how an object that partitions in two its thermally agitated environment relaxes to its equilibrium fluctuations. Event-driven molecular dynamics indicate that a conventional diffusive-like bound-Brownian motion is reached after a long-lived sub-diffusive regime. The two-stage behavior is not eliminated increasing the number of agitated particles, suggesting that the origin of the effect is a topologically frustrated exploration of phase-space. |
