On the role of a new type of correlated disorder in extended electronic states in the Thue-Morse lattice
Arunava Chakrabarti, S. N. Karmakar, R. K. Moitra
A new type of correlated disorder is shown to be responsible for the appearance of extended electronic states in one-dimensional aperiodic systems like the Thue-Morse lattice. Our…
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.,…
Extended electronic states in disordered 1-d lattices: an example
S. Sil, S. N. Karmakar, R. K. Moitra
We discuss a very simple model of a 1-d disordered lattice, in which {\em all} the electronic eigenstates are extended. The nature of these states is examined from several viewpoin…
Extended states in 1D lattices: application to quasiperiodic copper-mean chain
S. Sil, S. N. Karmakar, R. K. Moitra +1
The question of the conditions under which 1D systems support extended electronic eigenstates is addressed in a very general context. Using real space renormalisation group argumen…
