Conformal Field Theory Approach to the Two-channel Anderson Model
H. Johannesson, N. Andrei, C. J. Bolech
The two-channel Anderson impurity model serves as a prototype for describing heavy-fermion materials with a possible mixed-valent regime with both quadrupolar and magnetic characte…
Two-channel Anderson Impurity Model: Single-electron Green's function, self-energies, and resistivity
H. Johannesson, C. J. Bolech, N. Andrei
We compute exactly the low-energy single-electron Green's function, the impurity and electron self-energies, and the resistivity for the two-channel Anderson impurity model. These…
On the Multi-channel Anderson Model of Uranium Compounds
N. Andrei, C. J. Bolech
In this talk we will present the solution of the two-channel Anderson impurity model, proposed in the context of the heavy fermion compound UBe13, and discuss briefly the more gene…
Solution of the Multi-Channel Anderson Impurity Model: Ground state and thermodynamics
C. J. Bolech, N. Andrei
We present the solution of the SU(N) x SU(M) Anderson impurity model using the Bethe-Ansatz. We first explain what extensions to the formalism were required for the solution. Subse…
Critical Theory of the Two-Channel Anderson Impurity Model
H. Johannesson, N. Andrei, C. J. Bolech
We construct the boundary conformal field theory that describes the low-temperature behavior of the two-channel Anderson impurity model. The presence of an exactly marginal operato…
Cellular Dynamical Mean Field Theory for the 1D Extended Hubbard Model
C. J. Bolech, S. S. Kancharla, G. Kotliar
We explore the use of exact diagonalization methods for solving the self consistent equations of the cellular dynamical mean field theory (CDMFT) for the one dimensional regular an…
