文摘
- •
The electronic transport is analyzed by means of the Kubo-Greenwood formula.
- •
A new real-space renormalization method is developed for the participation ratio.
- •
The ballistic AC conductivity can be improved in generalized Fibonacci lattices.
- •
A renormalization plus convolution method is used for quasiperiodic nanowires.
- •
Participation ratio seems to be not proper for the analysis of critical states.
