A renormalization group analysis of extended electronic states in 1d quasiperiodic lattices
Arunava Chakrabarti, S. N. Karmakar, R. K. Moitra
We present a detailed analysis of the nature of electronic eigenfunctions in one-dimensional quasi-periodic chains based on a clustering idea recently introduced by us [Sil et al.,…
