Abstract For the localization of electronic states of one-dimensional quasilattices, two kinds of methods extensively used (KKT renormalization-group method and numerical simulation methods) have given contradictory, results. In this paper, an approach based on the transfer matrix method is adopted to deal with this problem in general. We confirm that the above two methods describe the ideal infinite quasilattices in different asymptotical ways. so different results are obtained. We also study analytically the localization of the zero-energy electronic states of the one-dimensional quasilattices, and provide some new results different from that of the previous work.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
