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. In the several-atom cluster case, one again can reformulate the ...
