Incipient antiferromagnetism and low-energy excitations in the half-filled two-dimensional Hubbard model
J. J. Deisz, D. W. Hess, J. W. Serene
We present single-particle and thermodynamic properties of the half-filled single-band Hubbard model in 2D calculated in the self-consistent fluctuation exchange approximation. The…
Low-Energy Excitations in an Incipient Antiferromagnet
D. W. Hess, J. J. Deisz, J. W. Serene
We present fully self-consistent calculations in the fluctuation exchange approximation for the half-filled Hubbard model in 2D. A non-fermi liquid state evolves with decreasing te…
Improved Treatment of Frequency Sums in Propagator-Renormalized Perturbation Theories
J. J. Deisz, D. W. Hess, J. W. Serene
We present a massively parallel algorithm for calculating the self-energy in self-consistent finite temperature perturbation theory for lattice models. The algorithm uses analytic…
Pseudogap Formation in the Symmetric Anderson Lattice Model
P. G. McQueen, D. W. Hess, J. W. Serene
We present self-consistent calculations for the self-energy and magnetic susceptibility of the 2D and 3D symmetric Anderson lattice Hamiltonian, in the fluctuation exchange approxi…
