Superconductivity Induced by Negative Centers
G. Litak, T. Paiva, R. T. Scalettar +2
We study the effect of random dilution of attraction centers on electron pairing in a generalization of the negative Hubbard model where the interaction , defined on the t…
Doping-dependent study of the periodic Anderson model in three dimensions
Thereza Paiva, Gokhan Esirgen, Richard T. Scalettar +2
We study a simple model for -electron systems, the three-dimensional periodic Anderson model, in which localized states hybridize with neighboring states. The states…
Quantum critical point in a periodic Anderson model
Peter van Dongen, Kingshuk Majumdar, Carey Huscroft +1
We investigate the symmetric Periodic Anderson Model (PAM) on a three-dimensional cubic lattice with nearest-neighbor hopping and hybridization matrix elements. Using Gutzwiller's…
Signatures of Spin and Charge Energy Scales in the Local Moment and Specific Heat of the Two-Dimensional Hubbard Model
Thereza Paiva, R. T. Scalettar, Carey Huscroft +1
Local moment formation driven by the on--site repulsion is one of the most fundamental features in the Hubbard model. At the simplest level, the temperature dependence of the l…
The Dynamical Cluster Approximation: A New Technique for Simulations of Strongly Correlated Electron Systems
S. Moukouri, C. Huscroft, M. Jarrell
We present the algorithmic details of the dynamical cluster approximation (DCA) algorithm. The DCA is a fully-causal approach which systematically restores non-local correlations t…
Pseudogaps in the 2D half-filled Hubbard model
C. Huscroft, M. Jarrell, Th. Maier +2
We study the pseudogaps in the spectra of the half-filled 2D Hubbard model using both finite-size and dynamical cluster approximation (DCA) quantum Monte Carlo calculations. A char…
