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…

Single-particle spectra and magnetic susceptibility in the Emery model: a dynamical mean-field perspective
Yi-Ting Tseng, Mário O. Malcolms, Henri Menke +3
We investigate dynamical mean-field calculations of the three-band Emery model at the one- and two-particle level for material-realistic parameters of high- superconductors. O…

Thermodynamic Stability at the Two-Particle Level
A. Kowalski, M. Reitner, L. Del Re +6
We show how the stability conditions for a system of interacting fermions that conventionally involve variations of thermodynamic potentials can be rewritten in terms of one- and t…
