Transmission And Reflection

Quantum interference effects for a mesoscopic loop with three leads are investigated by using a one-dimensional quantum waveguide theory. The transmission and reflection probabilities are analytically obtained in terms of the magnetic flux, arm length, and wave vector. Oscillation of the magnetoconductance is explicitly demonstrated. Magnetoconductance is found to be sharply peaked for certain localized values of flux and kl. In addition, it is noticed that the periodicity of the transmission probability with respect to kl depends more sensitively on the lead position, compared to the case of the two-lead loop.

Mesoscopic Structure

In this paper, the electronic transport properties of a four-terminal mesoscopic structure with a ring are studied by quantum waveguide theory. We show that the transmission coefficients of the three outgoing exits oscillate periodically with the distance between nodes and the magnetic flux threading the loop, and they share a common periodicity. However, there are differences in the magnitude and the position of their peaks. The transmission coefficient of the outgoing exit nearest to the incident port accounts for the greatest contribution to the total transmission coefficient.

Aharonov Bohm

A one-dimensional quantum waveguide theory is developed for a mesoscopic ring subject to the Aharonov–Casher(AC) effect based on the SU (2) spin gauge theory. The quantum interference by the AC effect is found to be equivalent to that by the Aharonov–Bohm(AB) effect. This indicates that AC effect can be utilized for device application in a very similar manner to the AB effect. The transmission probability induced by the AC effect is shown to be identical for the spin up and down components.
