Coherent cellular dynamical mean-field theory: a real-space quantum embedding approach to disorder in strongly correlated electron systems
Patrick Tscheppe, Marcel Klett, Henri Menke +4
We formulate a quantum embedding algorithm in real-space for the simultaneous theoretical treatment of nonlocal electronic correlations and disorder, the coherent cellular dynamica…

How to read between the lines of electronic spectra: the diagnostics of fluctuations in strongly correlated electron systems
T. Schäfer, A. Toschi
While calculations and measurements of single-particle spectral properties often offer the most direct route to study correlated electron systems, the underlying physics may remain…

Real-space cluster dynamical mean-field theory: Center focused extrapolation on the one- and two particle level
Marcel Klett, Nils Wentzell, Thomas Schäfer +4
We revisit the cellular dynamical mean-field theory (CDMFT) for the single band Hubbard model on the square lattice at half filling, reaching real-space cluster sizes of up to 9 x…
