An improved Green's function algorithm applied to quantum transport in carbon nanotubes
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
The renormalization-decimation algorithm (RDA) of López Sancho et al. is used in quantum transport theory to calculate bulk and surface Green's functions. We derive an improved ver…

Improved recursive Green's function formalism for quasi one-dimensional systems with realistic defects
Fabian Teichert, Andreas Zienert, Jörg Schuster +1
We derive an improved version of the recursive Green's function formalism (RGF), which is a standard tool in the quantum transport theory. We consider the case of disordered quasi…
