Generalized Wiedemann-Franz law in a two-site charge Kondo circuit: Lorenz ratio as a manifestation of the orthogonality catastrophe
نویسندگان
چکیده
We show that the transport integrals of two-site charge Kondo circuits connecting various multi-channel simulators satisfy generalized Wiedemann-Franz law with universal Lorenz ratios all greater than one. The magic are directly related to Anderson's orthogonality catastrophe in quantum providing some additional measure for strong electron-electron correlations. present a full fledged theory and discuss possible routes experimental verifications theory.

15 صفحه اولLarge violation of the Wiedemann-Franz law in Luttinger liquids.
We show that in weakly disordered Luttinger liquids close to a commensurate filling the ratio of thermal conductivity kappa and electrical conductivity sigma can deviate strongly from the Wiedemann-Franz law valid for Fermi liquids scattering from impurities. In the regime where the umklapp scattering rate Gamma(U) is much larger than the impurity scattering rate Gamma(imp), the Lorenz number L...
متن کاملViolation of the Wiedemann-Franz Law in Hydrodynamic Electron Liquids.
The Wiedemann-Franz law, connecting the electronic thermal conductivity to the electrical conductivity of a disordered metal, is generally found to be well satisfied even when electron-electron (e-e) interactions are strong. In ultraclean conductors in the hydrodynamic regime, however, large deviations from the standard form of the law are expected, due to the fact that e-e interactions affect ...
متن کاملFailure of the Wiedemann-Franz law in mesoscopic conductors
We study the effect of mesoscopic fluctuations on the validity of the Wiedemannn-Franz WF law for quasi-one-dimensional metal wires and open quantum dots. At temperatures much less than the generalized Thouless energy, Ec, the WF law is satisfied for each specific sample, but as the temperature is raised through Ec, a sample-specific correction to the WF law of order 1/g appears g is the dimens...
