Abstract

The recent experimental discovery of anomalous soft edge magnetoplasmons (EMP) in 2D charged systems 1,2 and the problem of their identification requires an analysis of their physical nature. We consider three different scenarios for the appearance of soft EMP modes proposed by different authors. Our analysis indicates that the anomalous soft modes reported in Ref. 2 have the smooth variation of the charge density near the edge of the 2D system as their origin, although other satellite modes remain unexplained.
