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…
