Mode-locking steps appear in ac-driven vortex lattices with random pinning. The behavior depends on frequency, transitioning from requiring higher forces at low frequencies to any force at high frequencies.

Area of Science:

  • Condensed Matter Physics
  • Materials Science

Background:

  • Vortex lattices in superconductors and superfluids exhibit complex dynamics under external driving forces.
  • Random pinning centers significantly influence the stability and flow behavior of these lattices.

Purpose of the Study:

  • To investigate the phenomenon of mode-locking in ac-driven vortex lattices with random pinning.
  • To understand the relationship between frequency, driving force amplitude, and the emergence of mode-locking.
  • To characterize the temporal order and depinning dynamics associated with different mode-locking regimes.

Main Methods:

  • Simulations of current-voltage characteristics for ac-driven vortex lattices.
  • Analysis of temporal order in different regimes without ac drive.
  • Characterization of the mode-locked state as a pinned frozen solid.

  • Investigation of depinning dynamics, including plastic flow and hysteresis.

    • Main Results:

    • Observed distinct mode-locking steps in simulated current-voltage characteristics.
    • Found that low frequencies require a finite ac force amplitude for mode-locking.
    • Determined that high frequencies exhibit mode-locking even with small ac force amplitudes.
    • Correlated mode-locking regimes with the nature of temporal order in the absence of ac drive.
    • Identified the mode-locked state as a pinned frozen solid in a moving reference frame.
    • Observed plastic flow and hysteresis during depinning from the mode-locked steps.

    Conclusions:

    • The frequency of the ac drive critically determines the conditions for mode-locking in randomly pinned vortex lattices.
    • The temporal order in the absence of driving forces provides insight into the observed mode-locking behaviors.
    • Depinning from these mode-locked states is a complex process involving plastic flow and hysteresis, characteristic of disordered systems.
