Quasiparticle Band Structure and Density Functional Theory: Single-Particle Excitations and Band Gaps in Lattice Models
D. W. Hess, J. W. Serene
We compare the quasiparticle band structure for a model insulator obtained from the fluctuation exchange approximation (FEA) with the eigenvalues of the corresponding density funct…

Coupled electrons and pair fluctuations in two dimensions: a transition to superconductivity in a conserving approximation
J. J. Deisz, D. W. Hess, J. W. Serene
We report on a fully self-consistent determination of a phase transition to a superconducting state in a conserving approximation. The transition temperature calculated for a two-d…

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…
