✦ Synopsis

We consider a one dimensional discrete Schrodi,lger equation with a quasiperiodic potential which exhibits mobility edges. [!sing multifractal analysis we show that the states at the mobility edge have a stable multifractal spectrum. Further, we show that the transition from extevded to localized states can be described by using the width of tile nmltifractal spectrum as an order parameter.
