We discovered a new way topological defects form in U(1) models, differing from the Kibble-Zurek mechanism. This finding, confirmed by simulations, has implications for superconductor experiments.

Area of Science:

  • Theoretical Physics
  • Condensed Matter Physics

Background:

  • Topological defects are crucial in understanding phase transitions.
  • The Kibble-Zurek mechanism explains defect formation in global theories.

Purpose of the Study:

  • To propose and investigate a novel mechanism for topological defect formation.
  • To explore defect formation in a U(1) model with local gauge symmetry.

Main Methods:

  • Theoretical modeling of defect formation in a U(1) gauge theory.
  • Numerical simulations to confirm theoretical predictions.

Main Results:

  • A new mechanism for topological defect formation was identified.
  • Predictions from this new mechanism were confirmed via numerical simulations.

  • The proposed mechanism yields distinct predictions compared to the Kibble-Zurek mechanism.

    • Conclusions:

    • The new mechanism provides a framework for understanding defect formation in local gauge theories.
    • Experimental verification is possible in superconductor systems.
    • The mechanism is potentially generalizable to more complex theoretical models.
