Description
There has been recently great interest in two particular vibrational modes of incommensurate (I) systems: phasons and amplitudons. In this letter we show that for a 1D incommensurate system phasons and amplitudons can be obtained with the simplest possible model: that of harmonic interactions between first neighbours only, provided that a realistic dependence of the force constants k with distance r is used
