Variational QMC study of a Hydrogen atom in jellium with comparison to LSDA and LSDA-SIC solutions
Andrew I. Duff, James F. Annett
A Hydrogen atom immersed in a finite jellium sphere is solved using variational quantum Monte Carlo (VQMC). The same system is also solved using density functional theory (DFT), in…

Quasipartice Spectra in the Hubbard Model
William H. Beere, James F. Annett
We examine the quasiparticle lifetime and spectral weight near the Fermi surface in the two-dimensional Hubbard model. We use the FLEX approximation to self-consistently generate t…
