Probe-Configuration-Dependent Decoherence in an Aharonov-Bohm Ring

概要

• 論文の詳細を見る

• We have measured transport through mesoscopic Aharonov-Bohm (AB) rings with two different four-terminal configurations. While the amplitude and the phase of the AB oscillations are explained well within the framework of the Landauer-Buttiker formalism, it is found that the probe configuration strongly affects the coherence time of the electrons, i.e., the decoherence is strongly reduced in the configuration of so-called nonlocal resistance. This result should provide an important clue in clarifying the mechanism of quantum decoherence in solids.
