Velocity Inversion with an Iterative Normal Incidence Point (NIP) Wave Tomography with Model-Based Common Diffraction Surface (CDS) Stack

Normal Incidence Point (NIP) wave tomography inversion has been recently developed to generate a velocity model using Common Reflection Surface (CRS) attributes, which is called the kinematic wavefield attribute. In this paper, we propose to use the model based Common Diffraction Surface (CDS) stack method attributes instead of data driven Common Reflection Surface attributes as an input data p...

ساختار الکترونی ترکیبات فرمیون سنگین M = Co, Rh) PuMGa5 )

 Electronic properties of heavy Fermion superconductors PuCoGa5 and PuRhGa5 consisting of density of states, band structure and the Fermi surface have been calculated based on density functional theory in the local spin density approximation plus on site Coulomb correlation (LSDA+U). Calculated density of states is in overall consistency with a photo emission experiment. The bands with f charac...

Improved Power Counting and Fermi Surface Renormalization *

The naive perturbation expansion for many-fermion systems is infrared divergent. One can remove these divergences by introducing counterterms. To do this without changing the model, one has to solve an inversion equation. We call this procedure Fermi surface renormalization (FSR). Whether or not FSR is possible depends on the regularity properties of the fermion self{energy. When the Fermi surf...

Regularity of Interacting Nonspherical Fermi Surfaces: The Full Self–Energy

Regularity of the deformation of the Fermi surface under short-range interactions is established to all orders in perturbation theory. The proofs are based on a new classification of all graphs that are not doubly overlapping. They turn out to be generalized RPA graphs. This provides a simple extension to all orders of the regularity theorem of the Fermi surface movement proven in [FST2]. Model...
