Colloidal spheres in an optical vortex trap exhibit unexpected collective motion. Quenched disorder induces a transition to a chaotic dynamical state with power-law scaling, revealing insights into weak chaos.

Area of Science:

  • Soft Matter Physics
  • Optical Trapping
  • Fluid Dynamics

Background:

  • Hydrodynamic coupling can induce collective motion in colloidal spheres.
  • Optical vortex traps are used to manipulate particles.

Purpose of the Study:

  • Investigate the dynamics of colloidal spheres in an optical vortex trap.
  • Explore the effect of quenched disorder on collective motion.

Main Methods:

  • Simulated three fluid-borne colloidal spheres.
  • Utilized a ringlike optical vortex trap.
  • Analyzed phase-space trajectories and collective fluctuations.

Main Results:

  • Observed a transition to a dynamical state driven by quenched disorder.

  • Characterized power-law divergence in phase-space trajectories.
  • Identified collective fluctuations with noninteger exponents.

    • Conclusions:

    • Quenched disorder induces weak chaos in the colloidal sphere system.
    • Observed scaling relationships link microscopic and macroscopic dynamics.
    • Findings are consistent with theoretical predictions for chaotic systems.
