Heat transport and thermal rectification in quasi-one-dimensional systems
E. Diaz, R. Gutierrez, G. Cuniberti
In this work we investigate heat conduction along a ladder-model conformed by two coupled one dimensional lattices with different anharmonicity. We study how the interchain couplin…
Environment effects on the electric conductivity of the DNA
A. V. Malyshev, E. Diaz, F. Dominguez-Adame +1
We present a theoretical analysis of the environment effects on charge transport in double-stranded synthetic poly(G)-poly(C) DNA molecules attached to two ideal leads. Coupling of…
Stable Bloch oscillations of cold atoms with time-dependent interaction
C. Gaul, R. P. A. Lima, E. Diaz +2
We investigate Bloch oscillations of interacting cold atoms in a mean-field framework. In general, atom-atom interaction causes dephasing and destroys Bloch oscillations. Here, we…
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)…
