Abstract: We formulate a quantum embedding algorithm in real-space for the simultaneous theoretical treatment of nonlocal electronic correlations and disorder, the coherent cellular dynamical mean-field theory (C-CDMFT). This algorithm combines the molecular coherent potential approximation (CPA)… read more here.

Abstract: Quantum embedding methods have become a powerful tool to overcome deficiencies of traditional quantum modelling in materials science. However while these are systematically improvable in principle, in practice it is rarely possible to achieve rigorous… read more here.
