Collision-induced coherent dynamics

TL;DR

This paper introduces a novel method to induce coherence in non-driven oscillators through physical collisions, demonstrated experimentally with a Newton's cradle setup, highlighting a new mechanism for coherence without sustained coupling.

Contribution

It presents the concept of collision-induced coherence, showing how strong, intermittent interactions can generate coherence in oscillators, differing from traditional sustained coupling methods.

Findings

Coherence achieved via physical collisions in oscillators.

Experimental validation using electrical and optical studies.

Demonstration under ambient and vacuum conditions.

Abstract

In this paper we demonstrate a route to develop coherence in a system of non-driven oscillators. Here, the coherence is brought about via physical collisions through which the oscillators exchange energy. While coherence in the classical situations occurs due to sustained coupling terms in the dynamical equations, collision-induced coherence is enabled solely through strong interactions that are of intermittent nature! We demonstrate this in a Newton's cradle arrangement of oscillators by electrical and optical studies under ambient and vacuum conditions.
