Effective low-energy model for f-electron delocalization.
We consider a periodic Anderson model (PAM) with a momentum-dependent interband hybridization that is strongly suppressed near the Fermi level. Under these conditions, we reduce the PAM to an effective low-energy Hamiltonian, H(eff), by expanding in the small parameter V0/t (V0 is the maximum interband hybridization amplitude and t is the hopping integral of the broadband). The resulting model ...

متن کاملLow-energy electron potentiometry.
In a lot of systems, charge transport is governed by local features rather than being a global property as suggested by extracting a single resistance value. Consequently, techniques that resolve local structure in the electronic potential are crucial for a detailed understanding of electronic transport in realistic devices. Recently, we have introduced a new potentiometry method based on low-e...
متن کاملLow Energy Effective Lagrangian of the Bess Model
In this paper the low energy limit of the BESS model is studied in a systematic way. The method consists in eliminating the heavy vector field, by use of its classical equations of motion, in the infinite mass limit. After the elimination of the heavy degrees of freedom we get additional terms to the Standard Model lagrangian. After a finite renormalization of the ordinary gauge bosons wave fun...
متن کاملLow-Energy Electron Diffraction Amplitudes for a "Bare-Substrate" Model
A theory of low-energy electron dif fraction (LEED) amplitudes is developed for a model in which the crystal surface is represented by a step-function termination of the bulk crystal potential ("bare-substrate" mode l ) . The crystal is considered to be centro-symmetric and it is assumed that either the crystal has a two-fold axis of rotation normal to the surface or the primay beam is normally...
