Fragility of the Kondo insulating gap against disorder: Relevance to recent puzzles in topological Kondo insulators
Kondo insulators are strongly correlated systems in which a clean insulating gap emerges only at very low temperature due to many-body effects involving localized f electrons. However, certain Kondo insulators, like SmB_{6} and Ce_{3}Bi_{4}Pt_{3}, display metallic behaviors at extremely low temperat...
