1 Dec 1994 | | Abstract: | Conductance through weak constrictions in Luttinger liquids is shown to vanish with frequency $omega$ as $c_1 omega^2 + c_2 omega^{2/g - 2}$, where $g$ is a dimensionless parameter characterizing the Luttinger liquid phase, and $c_1$ and $c_2$ are nonuniversal constants. The first term arises from the ^^ Coulomb blockade’ effect and dominates for $g < 1/2$, whereas the second results from eliminating high-energy modes and dominates for $g > 1/2$. | | Source: | arXiv, cond-mat/9411130 | | Services: | Forum | Review | PDF | Favorites | |
