RT Journal Article T1 Physical nature of critical modes in Fibonacci quasicrystals A1 Maciá Barber, Enrique Alfonso AB We report on the possibility of modulating the transport properties of critical normal modes in Fibonacci quasicrystals by using the mass ratio as a tuning parameter. The relationship between the spatial structure and the transport properties of these modes is studied analytically in terms of the transmission and Lyapunov coefficients. Power spectrum analysis of the critical modes indicates a complex modulated structure in agreement with previous experimental results, [S0163-1829(99)11337-7].
