- Abstract
The transmission coefficient of a nanodevice-a quantum ring with two one-dimensional conductors attached-is found. The Hamiltonian of a nanodevice is constructed in terms of the theory of self-adjoint extensions of symmetric operators. It is shown that, in this case, the transmission coefficient coincides with that determined by the Feynman sum rule for the probability amplitudes. The transmission coefficient of the nan-odevice is studied as a function of the electron energy, magnetic field, and the relative positions of the conductor contacts and the ring.
