Interferometry using spatial adiabatic passage in quantum dot networks
journal contribution
posted on 2023-05-18, 12:37 authored by Lenneke JongLenneke Jong, Greentree, ADWe show that techniques of spatial adiabatic passage can be used to realize an electron interferometer in a geometry analogous to a conventional Aharonov-Bohm ring, with transport of the particle through the device modulated using coherent transport adiabatic passage. This device shows an interesting interplay between the adiabatic and nonadiabatic behavior of the system. The transition between nonadiabatic and adiabatic behavior may be tuned via system parameters and the total time over which the protocol is enacted. Interference effects in the final state populations analogous to the electrostatic Aharonov-Bohm effect are observed.
