Absence of extended states in a ladder model of DNA
E. Diaz, A. Sedrakyan, D. Sedrakyan +1
We consider a ladder model of DNA for describing carrier transport in a fully coherent regime through finite segments. A single orbital is associated to each base, and both interst…
Wannier-Stark ladder in the linear absorption of a random system with scale-free disorder
E. Diaz, F. Dominguez-Adame, Yu. A. Kosevich +1
We study numerically the linear optical response of a quasiparticle moving on a one-dimensional disordered lattice in the presence of a linear bias. The random site potential is as…
Anomalous optical absorption in a random system with scale-free disorder
E. Diaz, A. Rodriguez, F. Dominguez-Adame +1
We report on an anomalous behavior of the absorption spectrum in a one-dimensional lattice with long-range-correlated diagonal disorder with a power-like spectrum in the form S(k)…
