From Tomonaga-Luttinger to Fermi liquid in transport through a tunneling barrier | | Vadim Ponomarenko

24 Sep 1997 | | Subject: | cond-mat | | Affiliation: | A.F.Ioffe PTI, Petersburg) and Naoto Nagaosa (Department of Applied Physics, University of Tokyo | | Abstract: | Finite length of a one channel wire results in crossover from a Tomonaga-Luttinger to Fermi liquid behavior with lowering energy scale. In condition that voltage drop $(V)$ mostly occurs across a tunnel barrier inside the wire we found coefficients of temperature/voltage expansion of low energy conductance as a function of constant of interaction, right and left traversal times. At higher voltage the finite length contribution exhibits oscillations related to both traversal times and becomes a slowly decaying correction to the scale-invariant $V^{1/g-1}$ dependence of the conductance. | | Source: | arXiv, cond-mat/9709262 | | Services: | Forum | Review | PDF | Favorites | |
