Method of calculations for electron transport in multiterminal quantum systems based on real-space lattice models
A formalism for the calculations of electron transport in multiterminal quantum systems is presented. The systems are described by tight-binding Hamiltonians. It is shown that by exploiting real-space Green's functions, a problem of the electron transport in a multiterminal system can be reformulated into a problem of the electron transport in an effective two-terminal system and can then be treat
