| Abstract: | In this paper we have studied the spreading of an electronic wave packet one-dimensional tight-binding systems. Also we studied the relations between the spreading of an electronic wave packet and the system's dynamics behavior. We have compared the Fibonacci system with Anderson system in electronic wave functions and the probability density to find a method for analyzing the dynamics of quasiperiodic systems. |
