Antiferromagnetic Domains and Superconductivity in UPt3
Matthias J. Graf, Daryl. W. Hess
We explore the response of an unconventional superconductor to spatially inhomogeneous antiferromagnetism (SIAFM). Symmetry allows the superconducting order parameter in the E-repr…
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…
Single-Particle Excitations in a Two-Dimensional Strong-Coupling Superconductor
D. W. Hess, J. J. Deisz, J. W. Serene
We present calculations of the single-particle excitation spectrum for a 2D strong-coupling superconductor in a conserving approximation. Spectral weight at low frequency is substa…
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…
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…
