Flat band states: Disorder and nonlinearity

Leykam, Daniel; Flach, Sergej; Bahat-Treidel, Omri; Desyatnikov, Anton S


We study the critical behavior of Anderson localized modes near intersecting flat and dispersive bands in the quasi-one-dimensional diamond ladder with weak diagonal disorder W. The localization length ξ of the flat band states scales with disorder as ξ
