Witrynaone impure cluster might have both an impurity problem and a dispersion problem. In order to minimize the impurity of a cluster, we need to suppress both problems. Im p i should be a compound coefficient that penalizes both problems. To penalize the impurity problem is actually penalizing the uncertainty of the cluster label. Witryna23 kwi 2024 · In such situations, in DMFT instead of one-atom impurity problem one needs to solve an “impurity cluster” problem. Technically, the cluster problem is very similar to the many-orbital problem from the last section, where all functions are matrices in the orbital indices.
