Researchers observed unexpected energy-dependent behavior in electron interferometers. The Aharonov-Bohm (AB) oscillation amplitude showed distinct lobes with zeros, and phase slips occurred at these zeros, revealing a new energy scale for quantum coherence.

Area of Science:

  • Condensed Matter Physics
  • Quantum Electronics

Background:

  • The Mach-Zehnder interferometer is a fundamental tool in optics.
  • Quantum Hall effect provides a unique system for studying electron behavior in 2D systems.
  • Aharonov-Bohm (AB) oscillations demonstrate the wave nature of electrons.

Purpose of the Study:

  • To investigate the behavior of electron interferometers in the quantum Hall regime.
  • To explore the energy dependence of Aharonov-Bohm oscillations.
  • To characterize the observed unpredictable behavior and its implications for quantum coherence.

Main Methods:

  • Constructed an electronic analog of the Mach-Zehnder interferometer.
  • Utilized current-carrying edge channels in the quantum Hall effect regime.
  • Measured Aharonov-Bohm oscillations and their energy dependence.

Main Results:

  • Observed high-contrast Aharonov-Bohm oscillations.
  • Found that oscillation amplitude varied with energy in a distinct "lobe" pattern with maxima and zeros.
  • Noted abrupt phase slips of pi at oscillation zeros.
  • Identified a new energy scale related to lobe periodicity.

Conclusions:

  • The observed lobe structure and phase slips represent an unpredictable behavior in electron interferometry.
  • This behavior suggests a new characteristic energy scale for quantum coherence in interfering electrons.
  • The findings may offer new insights into fundamental quantum phenomena.
