We derived a general expression for adiabatic pumped charge in superconducting nanocircuits. This relates to non-Abelian holonomies, with experimental implications for coherent quantum processes.

Area of Science:

  • Condensed matter physics
  • Quantum mechanics
  • Nanotechnology

Background:

  • Cooper pair pumping is a fundamental coherent quantum process in superconducting nanocircuits.
  • Understanding adiabatic charge transport is crucial for quantum information processing and metrology.
  • Level degeneracy in quantum systems introduces complex behaviors in adiabatic evolution.

Purpose of the Study:

  • To derive a general expression for adiabatic pumped charge in superconducting nanocircuits with level degeneracy.
  • To establish a connection between adiabatic pumped charge and non-Abelian holonomies.
  • To identify experimental systems where non-Abelian structures are observable in pumped charge.

Main Methods:

  • Theoretical derivation of pumped charge using quantum mechanical principles.

    • The pumped charge was directly related to non-Abelian holonomies.
    • An experimental scenario was proposed where the non-Abelian structure is manifested in the pumped charge.

    Conclusions:

    • The study provides a theoretical framework for understanding adiabatic charge pumping in degenerate superconducting nanocircuits.
    • Non-Abelian holonomies offer a powerful tool to describe complex adiabatic processes in these systems.
    • The findings pave the way for experimental verification and potential applications in quantum technologies.
