- 論文の詳細を見る
We investigate the effect of electron-electron interactions on the transport properties of dis-ordered quasi one-dimensional quantum wires with two or more subbands occupied. We applytwo alternative methods to solve the logarithmic divergent problem, namely the parquet graphtheory and a renormalization group calculation. We solve the group equations analytically inthe weak coupling limit and find a power law for the temperature dependent conductivity ofa multi-channel system. The exponent is roughly equal to the inverse of the number of theoccupied subbands.
