The Dynamical Cluster Approximation: Non-Local Dynamics of Correlated Electron Systems
M. H. Hettler, M. Mukherjee, M. Jarrell +1
We recently introduced the dynamical cluster approximation(DCA), a new technique that includes short-ranged dynamical correlations in addition to the local dynamics of the dynamica…
