Aharonov–Bohm Phase Shifts Induced by Laser Pulses
An experimentally accessible scalar Aharonov–Bohm (AB)-effect is proposed using a ponderomotive potential induced by a pulsed laser. This ponderomotive AB (PAB)-effect is unique in that the time-averaged description is classified as type-I, whereas the underlying time-dependent theory is classified as type-II. Not only is the PAB-effect of fundamental interest, it may also be used to characteri...
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 کاملSemiclassical Explanation of the Matteucci–Pozzi and Aharonov–Bohm Phase Shifts
When a line of dipoles is placed between the beams of electrons forming an interference pattern, there is a shift in the interference pattern. In the case of a line of electric dipoles, the interference pattern shift was observed experimentally by Matteucci and Pozzi. (1) In the case of a line of magnetic dipoles (a solenoid), the phase shift was suggested by Aharonov and Bohm (2) and was first...
متن کاملPhase of Aharonov-bohm Oscillations in Conductance of Mesoscopic Systems
Motivated by a recent experiment we analyze in detail the phase of Aharonov-Bohm oscillations across a 1D ring with a stub coupled to one of its arms, in the presence of a magnetic flux. We demonstrate that there are two kinds of conductance extremas. One class of them are fixed at particular flux values and can only change abruptly from a maxima to a minima as incident energy is varied. We sho...
متن کاملEffect of Aharonov-Bohm Phase on Spin Tunneling
The role of Aharonov-Bohm effect in quantum tunneling is examined when a potential is defined on the S1 and has N -fold symmetry. We show that the low-lying energy levels split from the N -fold degenerate ground state oscillate as a function of the Aharonov-Bohm phase, from which general degeneracy conditions depending on the magnetic flux is obtained. We apply these results to the spin tunneli...
