Flatband localization in the Anderson-Falicov-Kimball model
arXiv:0810.3585 · doi:10.1103/PhysRevB.79.153104
Abstract
The insulator-metal-insulator transition caused by a flatband is analyzed within dynamical mean-field theory using the Anderson-Falicov-Kimball model. We observe quantitative disagreement between the present approach and previous results. The presence of interactions enhances delocalization.
