Coulomb drag of luttinger liquids and quantum hall edges

Research output: Contribution to journalJournal articleResearchpeer-review

We study the transconductance for two coupled one-dimensional wires or edge states described by Luttinger liquid models. The wires are assumed to interact over a finite segment. We find for the interaction parameter g = 1/2 that the drag rate is finite at zero temperature, which cannot occur in a Fermi-liquid system. The zero temperature drag is, however, cut off at low temperature due to the finite length of the wires. We also consider edge states in the fractional quantum Hall regime, and suggest that low temperature enhancement of the drag effect might be seen in this regime.
