WebK-point integration. In this section we discuss partial occupancies. A must for all readers. First there is the question why to use partial occupancies at all. The answer is: partial occupancies help to decrease the number of k-points necessary to calculate an accurate band-structure energy. This answer might be strange at first sight.
