| Research Abstract |
We have performed first-principles calculations of quantum transport in nano contacts by using the recursion-transfer matrix method, the Lippmann-Schwinger method, and the nonequilibrium Green's function method. We have analyzed transport properties to reveal conduction channels. We have also developed the time-dependent wave-packet diffusion method, and have succeeded in the unified quantum transport calculation from ballistic to diffusive regime.
