Solids with Weak and Strong Electron Correlations
A number of methods are discussed which may serve for a treatment of electron correlations in solids. When the electron correlations are relatively weak like in semiconductors or a number of ionic crystals one may start from a self-consistent field calculation and include correlations by quantum chemical methods. An incremental computational scheme enables us to obtain results of high quality f...
متن کاملThe Electron-Phonon Interaction in the Presence of Strong Correlations
We investigate the effect of strong electron-electron repulsion on the electronphonon interaction from a Fermi-liquid point of view. In particular we show that the strong interaction is responsible for vertex corrections, which are strongly dependent on the vF q/ω ratio, where vF is the Fermi velocity and q and ω are the transferred momentum and frequency respectively. These corrections generic...

متن کاملSmoothness of correlations in the Anderson model at strong disorder
We study the higher-order correlation functions of covariant families of observables associated with random Schrödinger operators on the lattice in the strong disorder regime. We prove that if the distribution of the random variables has a density analytic in a strip about the real axis, then these correlation functions are analytic functions of the energy outside of the planes corresponding to...
