Effects of interactions in transport through Aharonov-Bohm-Casher interferometers.
We study the conductance through a ring described by the Hubbard model (such as an array of quantum dots), threaded by a magnetic flux and subject to Rashba spin-orbit coupling (SOC). We develop a formalism that is able to describe the interference effects as well as the Kondo effect when the number of electrons in the ring is odd. In the Kondo regime, the SOC reduces the conductance from the u...
متن کاملPhase measurements in Aharonov-Bohm interferometers
In this paper we address measurements of the resonant quantum transmission amplitude tQD = −i|tQD|e iαQD through a quantum dot (QD), as function of the plunger gate voltage V . Mesoscopic solid state Aharonov-Bohm interferometers (ABI) have been used to measure the “intrinsic” phase, αQD, when the QD is placed on one of the paths. In a “closed” interferometer, connected to two terminals, the el...
متن کاملPhase measurements in open and closed Aharonov-Bohm interferometers
Mesoscopic Aharonov-Bohm interferometers have been used in attempts to measure the transmission phase of a quantum dot which is placed on one arm of the interferometer. Here we review theoretical results for the conductance through such interferometers, for both the closed (two-terminal) and open (multi-terminal) cases. In addition to earlier results for the Coulomb blockade regime, we present ...
متن کاملTransport, Aharonov–Bohm, and Topological Effects in Graphene Molecular Junctions and Graphene Nanorings
The unique ultrarelativistic, massless, nature of electron states in two-dimensional extended graphene sheets, brought about by the honeycomb lattice arrangement of carbon atoms in two dimensions, provides ingress to explorations of fundamental physical phenomena in graphene nanostructures. Here, we explore the emergence of new behavior of electrons in atomically precise segmented graphene nano...
متن کاملComment on "Aharonov-Casher and scalar Aharonov-Bohm topological effects".
We reexamine the topological and nonlocal natures of the Aharonov-Casher and scalar Aharonov-Bohm phase effects. The underlying U(1) gauge structure is exhibited explicitly. And the conditions for developing topological Aharonov-Casher and scalar Aharonov-Bohm phases are clarified. We analyze the arguments of M. Peshkin and H. J. Lipkin [Phys. Rev. Lett. 74, 2847 (1995)] in detail and show that...
