Magneto-electric Aharonov–Bohm effect in metal rings

  title={Magneto-electric Aharonov–Bohm effect in metal rings},
  author={Alexander van Oudenaarden and Michel H. Devoret and Yuli V. Nazarov and Johann E. Mooij},
The quantum-mechanical phase of the wavefunction of an electron can be changed by electromagnetic potentials, as was predicted by Aharonov and Bohm in 1959. Experiments on propagating electron waves in vacuum have revealed both the magnetic and electrostatic Aharonov–Bohm effect. Surprisingly, the magnetic effect was also observed in micrometre-sized metal rings, demonstrating that electrons keep their phase coherence in such samples despite their diffusive motion. The search for the…

Electromagnetic Aharonov-Bohm effect in a two-dimensional electron gas ring
We define a mesoscopic ring in a two-dimensional electron gas interrupted by two tunnel barriers, enabling us to apply a well-defined potential difference between the two halves of the ring. The
Optical exciton Aharonov-Bohm effect, persistent current, and magnetization in semiconductor nanorings of type I and II
The optical exciton Aharonov-Bohm effect—i.e., an oscillatory component in the energy of optically active bright states—is investigated in nanorings. It is shown that a small effective electron mass,
High-temperature Aharonov-Bohm effect in transport through a single-channel quantum ring
We overview transport properties of an Aharonov-Bohm interferometer made of a single-channel quantum ring. Remarkably, in this setup, essentially quantum effects survive thermal averaging: the

Tuning the Aharonov-Bohm effect with dephasing in nonequilibrium transport
The Aharanov-Bohm (AB) effect, which predicts that a magnetic field strongly influences the wave function of an electrically charged particle, is investigated in a three site system in terms of the
Aharonov--Bohm effect, electrodynamics postulates, and Lorentz condition
The problem of the relation between the Ahronov-Bohm effect and traditional postulates of electrodynamics, which claim that only electric and magnetic fields are observable, is resolved by denial of

It is demonstrated that magnetic fields which give rise to a magnetic flux comparable to 10(-3) of the quantum flux can be used to switch a class of different molecular and nanometer rings, ranging from quantum corrals, carbon nanotubes and even a molecular ring composed of polyconjugated aromatic materials.
Aharonov-Bohm effect in the tunnelling of a quantum rotor in a linear Paul trap.
It is demonstrated that the charged particles in this quantum Tunnelling system are coupled to the vector potential of a magnetic field throughout the entire process, even during quantum tunnelling, as indicated by the manifestation of the Aharonov-Bohm effect in this system.

The phase of the wave function of charged matter is sensitive to the value of the electric potential, even when the matter never enters any region with nonvanishing electromagnetic fields. Despite
