Condensed matter : an Institute of Physics journal 29: 155301 (2017) | Resumen: | We have performed time-dependent wave packet simulations of realistic Aharonov-Bohm (AB) devices with a quantum dot embedded in one of the arms of the interferometer. The AB ring can function as a measurement device for the intrinsic transmission phase through the quantum dot, however, care has to be taken in analyzing the influence of scattering processes in the junctions of the interferometer arms. We consider a harmonic quantum dot and show how the Darwin-Fock spectrum emerges as a unique pattern in the interference fringes of the AB oscillations. | Descripción: | 10 pags., 3, A1, B1 figs. | Versión del editor: | https://doi.org/10.1088/1361-648X/aa605d | URI: | http://hdl.handle.net/10261/162805 | DOI: | 10.1088/1361-648X/aa605d | Identificadores: | doi: 10.1088/1361-648X/aa605d issn: 1361-648X |
