| Outline of Final Research Achievements |
Quantum transportation had been discussed in quantum mechanics. In this work, it has studied in quantum field theory, which is an advanced theory over quantum mechanics. Particularly, local physical quantities, local conductance and spin vorticity density, defined in quantum field theory is used to analyze.
It has been shown that local conductance is consistent with the conductance of the Landauer formula by using models (benzenedithiol and graphene).
The linear relation between the spin vorticity density and electric current density is proposed and this relation has been confirmed in numerical computations for some models, such as helicene and graphene.
