N ov 1 99 8 Pairing in low - density Fermi gases

چکیده
We consider pairing in a dilute system of Fermions with a short-range interaction. While the theory is ill-defined for a contact interaction, the BCS equations can be solved in the leading order of low–energy effective field theory. The integrals are evaluated with the dimensional regularization technique, giving analytic formulas relating the pairing gap, the density, and the energy density to the two-particle scattering length.

متن کاملN ov 1 99 5 1 Rigorous Density Functional Theory for Inhomogeneous Bose - Condensed Fluids
The density functional theory originally developed by Hohenberg, Kohn and Sham provides a rigorous conceptual framework for dealing with inhomoge-neous interacting Fermi systems. We extend this approach to deal with in-homogeneous interacting Bose-condensed systems, limiting this presentation to setting up the formalism to deal with ground state (T = 0) properties. The key new feature is that o...
متن کاملov 2 00 3 Cooper Pairing Revisited
Doubtlessly the most central notion in superconductivity, for both low and high transition temperatures Tc, is that of Cooper pairs (CPs) [1] that form among the underlying electron (or hole) charge carriers of the many-electron system. And yet, it is perhaps the least understood concept. Shortly after the publication of the BCS theory [2] of superconductivity, charged pairs observed in magneti...

The paper compares the K-dependence of the superconducting gap in different doping ranges. The fine behavior of the leading edge gap indicates that the pairing susceptibility is peaked at special regions on the Fermi surface. These hot regions are found to be centered away from nominal " hot spots ". This behavior is attributed to a feedback effect on the pairing boson. Identification is made t...
متن کامل0 N ov 1 99 8 Single - particle properties of a model for coexisting charge and spin quasi - critical fluctuations coupled to electrons
We study the single-particle spectral properties of a model for coexisting AFM and ICDW critical fluctuations coupled to electrons, which naturally arises in the context of the stripe-quantum-critical-point scenario for high-T c superconducting materials. Within a perturbative approach, we show that the on-shell inverse scattering time deviates from the normal Fermi-liquid behavior near the poi...
