Double chains with base pairing: delocalization irrespective to DNA sequencing
R. A. Caetano, P. A. Schulz
The question of whether DNA is intrinsically conducting or not is still a challenge. The ongoing debate on DNA molecules as an electronic material has so far underestimated a key d…
Moving a perturbation across quantum dots: tuning of Fano resonances
M. Mendoza, P. A. Schulz
We propose a controllable way of tuning Fano resonances in open quantum dots in the absence of magnetic field. A quantum dot can be modified by changing the gate voltages that defi…
Level spacing statistics of disordered finite superlattices spectra and motional narrowing as a random matrix theory effect
R. R. Rey-Gonzalez, P. A. Schulz
In the present work the problem of coupled disordered quantum wells is addressed in a random matrix theory framework. The quantum wells are short repulsive binary alloys embeded by…
Intense AC field driven superlattices with barrier width dimerization
P. H. Rivera, N. Studart, P. A. Schulz
The evolution of two coupled mini-bands, generated by alternating barrier widths dimerization of a superlattice, driven by intense AC fields is investigated. The present model deli…
Tuning of dynamic localization in coupled minibands: signatures of a field induced insulator-metal transition
P. H. Rivera, P. A. Schulz
We follow the evolution of dressed coupled mini-bands as a function of an AC field intensity, non perturbatively, for a wide field frequency range. High and low frequency limits ar…
