We use a bosonization approach to show that the momentum distribution nk of normal Fermi systems with sufficiently singular interactions is analytic in the vicinity of the non-interacting Fermi surface. These include singular density-density interactions that diverge in d dimensions stronger than |q|−2(d−1) for vanishing momentum transfer q, but also fermions that are coupled to transverse gaug...
متن کاملNormal Fermi-Walker Derivative in E_{1}^{3}
In this paper, firstly, in $E_1^3$, we defined normal Fermi-Walker derivative and applied for the adapted frame. Normal Fermi-Walker parallelism, normal non-rotating frame, and Darboux vector expressions of normal Fermi-Walker derivative by normal Fermi-Walker derivative are given for adapted frame. Being conditions of normal Fermi-Walker derivative and normal non-rotating frame are examined fo...
متن کاملLow temperature analysis of two dimensional Fermi systems with symmetric Fermi surface
We prove the convergence of the perturbative expansion, based on Renormalization Group, of the two point Schwinger function of a system of weakly interacting fermions in d = 2, with symmetric Fermi surface and up to exponentially small temperatures, close to the expected onset of superconductivity.
متن کاملNon-Fermi Liquid in a Truncated Two-Dimensional Fermi Surface
Using perturbation theory and the field theoretical renormalization group approach we consider a two-dimensional anisotropic truncated Fermi Surface(FS) with both flat and curved sectors which approximately simulates the “cold” and “hot” spots in the cuprate superconductors. We calculate the one-particle two-loop irreducible functions Γ and Γ as well as the spin, the charge and pairing response...
متن کاملRG on a Fermi surface
We review the renormalization group (RG) method for interacting fermions, building off typical φ theory to account for the presence of a Fermi surface. A few geometries and the general procedure are briefly discussed. The method is illustrated with a model of two Fermi circles with different spin components and momenta, which can describe experiments with interacting fermions. General results o...
