Universal Behavior of Quantum Impurity Scattering in Tomonaga-Luttinger Liquid
Using bosonization and path integral methods, we study general low temperature behavior of non-magnetic and magnetic impurity scattering in Tomonaga-Luttinger liquid, and calculate electron Green function for a general backward scattering potential. We demonstrate that electron density of state near the impurity site is suppressed by the backward scattering, but it mainly remains invariant as f...
متن کاملCoupling between phonon-phonon and phonon-impurity scattering: A critical revisit of the spectral Matthiessen’s rule
The spectral Matthiessen’s rule is commonly used to calculate the total phonon scattering rate when multiple scattering mechanisms exist. Here we predict the spectral phonon relaxation time τ of defective bulk silicon using normal mode analysis based on molecular dynamics and show that the spectral Matthiessen’s rule is not accurate due to the neglect of the coupling between anharmonic phonon-p...
متن کاملMagnetic Impurity in a Luttinger Liquid : A
Exact results are reported for the low-temperature thermodynamics of a spin-1 2 magnetic impurity coupled to a 1D interacting electron system. The use of conformal eld theory techniques reveals that there are only two types of critical behaviors consistent with the symmetries of the problem: either a local Fermi liquid, or else a theory identical to that recently proposed by Furusaki and Nagaos...

متن کاملMagnetic Impurity in a Luttinger Liquid : A Conformal Field Theory
We study the low-temperature properties of a spin-1 2 magnetic impurity coupled to a one-dimensional interacting electron system. Using the newly developed formalism by AAeck and Ludwig, with a scale invariant boundary condition replacing the impurity, we exploit boundary conformal eld theory to deduce the impurity thermal and magnetic response. In the case of only forward electron scattering o...
