Flux-dependent Kondo temperature in an Aharonov-Bohm interferometer with an in-line quantum dot
Flux-dependent Kondo temperature in an Aharonov-Bohm interferometer with an in-line quantum dot
An Aharonov-Bohm interferometer (ABI) carrying a quantum dot on one of its arms is analyzed. It is found that the Kondo temperature of the device may depend strongly on the magnetic flux penetrating the ring. As a result, mesoscopic finite-size effects appear leading to plateaus in the finite-temperature conductance as …
