Bosonic effective action for interacting fermions
We present a bosonic description for systems of interacting fermions. A systematic expansion of the free energy starts with a solution to the lowest order Schwinger-Dyson or gap equation. Part of the phase diagram for the Hubbard model is computed in this framework. We propose a two particle irreducible formulation of an exact renormalization group equation for computations beyond leading order...
متن کاملInteracting fermions :
Most materials are either metals or insulators. When they are metals, their electronic properties are usually described by Landau's Fermi liquid theory. That is, they behave more or less like a free Fermi gas, with a few modifications due to electron-electron interactions. However, there exist a few metallic materials whose phenomenology does not fit within Fermi liquid theory. These are quasi-...
متن کاملHamiltonian renormalization of interacting fermions
The Bloch-Feshbach formalism known from the theory of nuclear dynamics allows one to understand renormalization in terms of purely algebraic operations (projections) in Hilbert space. This algebraic approach is put to the test in the study of the low-energy dynamics of interacting fermions and proves to be eecient in deriving such diverse results as Landau's theory for the eeective mass, the sc...
متن کاملInteracting staggered domain wall fermions
I remember it very clearly: It was a sunny spring Northern California afternoon in 1988. I had just passed my Ph.D. exams and was about to start research. My Ph.D. advisor took his other student (also my collaborator) and me out to lunch to the place across from the physics department. This was unusual, so it naturally weighed a lot. I do not remember his exact words, but he basically told us a...
متن کاملTunneling of Interacting Fermions in 1D Systems
Using the self-consistent Hartree–Fock approximation for spinless electrons at zero temperature, we study tunneling of the interacting electron gas through a single δ barrier in a finite one-dimensional wire connected to contacts. Our results exhibit features known from correlated many-body models. In particular, the conductance decays with the wire length as ∝ L−2α, where the power α is univer...
