A NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION
Authors: not saved
Abstract:
A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian

full textA numerical renormalization group approach for calculating the spectrum of a vibronic system occurring in molecules or impurities in insulators
Theoretically, in order to describe the behavior of a spectrum, a mathematical model whichcould predict the spectrum characteristics is needed. Since in this study a Two-state system has beenused like models which was introduced previously past and could couple with the environment, theformer ideas have been extended in this study. we use the second quantized version for writing thisHamiltonian...
full textRenormalization of the Drude conductivity by the electron-phonon interaction.
It is commonly believed that the Drude conductivity is not renormalized by many-body interactions. To the contrary, we show that for impure metals the Drude conductivity is decreased by a temperaturedependent factor proportional to the electron-phonon coupling l. We demonstrate this effect by both the linear response and the quantum transport approaches. This effect, while comparable to the bar...

We generalize the numerical renormalization group scheme of Ref. [Honerkamp et al.(2001)Honerkamp, Salmhofer, Furukawa, and Rice, Zanchi and Schulz(2000), Halboth and Metzner(2000)] to study the phonon-mediated retarded interactions in the high Tc cuprates. We find that three sets of phonon-mediated retarded quasiparticle scatterings grow under RG flow. These scatterings share the following com...

full textA Renormalization Group for Hamiltonians: Numerical Results
We describe a renormalization group transformation that is related to the breakup of golden invariant tori in Hamiltonian systems with two degrees of freedom. This transformation applies to a large class of Hamiltonians, is conceptually simple, and allows for accurate numerical computations. In a numerical implementation, we find a nontrivial fixed point and determine the corresponding critical...
