Researchers measured persistent currents in gold rings, revealing unexpected flux periodicities. These findings challenge existing theories and suggest a new approach involving phase coherence time saturation.

Area of Science:

  • Condensed Matter Physics
  • Mesoscopic Physics

Background:

  • Persistent currents in mesoscopic conductors are fundamental to understanding quantum phenomena.
  • Conventional theories predict specific flux periodicities (h/e, h/2e) based on electron behavior.

Purpose of the Study:

  • To experimentally investigate persistent currents in an array of diffusive mesoscopic gold rings.
  • To compare measured flux periodicities with theoretical predictions.

Main Methods:

  • Fabrication and measurement of an array of thirty diffusive mesoscopic gold rings.
  • Low-temperature measurements of diamagnetic persistent currents.
  • Analysis of flux periodicities (h/e and h/2e).

Main Results:

  • Observed both h/e and h/2e flux periodicities in the persistent current.

  • Current magnitudes per ring comparable to the Thouless energy (E(c)).
  • Results challenge conventional persistent current theories.

    • Conclusions:

    • The experimental findings necessitate a re-evaluation of current theoretical models.
    • A new theoretical approach, considering the saturation of phase coherence time (τ(φ)), is proposed.
