Collective excitation spectrum of a disordered Hubbard model
Yolande H. Szczech, Michael A. Tusch, David E. Logan
We study the collective excitation spectrum of a d=3 site-disordered Anderson-Hubbard model at half-filling, via a random-phase approximation (RPA) about broken-symmetry, inhomogen…

Insulating phases of the infinite-dimensional Hubbard model
David E. Logan, Michael P. Eastwood, Michael A. Tusch
A theory is developed for the T=0 Mott-Hubbard insulating phases of the infinite-dimensional Hubbard model at half-filling, including both the antiferromagnetic (AF) and paramagnet…
