The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

A passive harmonic chain can be transformed by its coupling to active matter into a self-sustained fluctuating medium with many-body Rayleigh-like dynamics, resulting in pulsations of the displacements, spatial oscillations, and the emergence of persistence in velocities along the chain.

C2weakest assumption

The derivation assumes time-scale separation between the fast run-and-tumble particle bath and the slower oscillator chain, allowing explicit averaging to obtain the induced Langevin dynamics with streaming term, friction coefficient, and noise amplitude.

C3one line summary

Coupling a passive harmonic oscillator chain to a persistent run-and-tumble particle bath induces negative friction, instability, and nonlinear stabilization into many-body Rayleigh-like self-sustained dynamics with pulsations and velocity persistence.
