Disorder enhanced transport as a general feature of long-range hopping models
Elisa Zanardini, Giuseppe Luca Celardo, Nahum C. Chávez +1
We analyze the interplay of disorder and long-range hopping in a paradigmatic one dimensional model of quantum transport. While typically the current is expected to decrease as the…
Universal stability of coherently diffusive 1D systems with respect to decoherence
F. S. Lozano-Negro, E. Alvarez Navarro, N. C. Chávez +4
Static disorder in a 3D crystal degrades the ideal ballistic dynamics until it produces a localized regime. This Metal-Insulator Transition is often preceded by coherent diffusion.…
Disorder-Enhanced and Disorder-Independent Transport with Long-Range Hopping: Application to Molecular Chains in Optical Cavities
Nahum C. Chávez, Francesco Mattiotti, J. A. Méndez-Bermúdez +2
Overcoming the detrimental effect of disorder at the nanoscale is very hard since disorder induces localization and an exponential suppression of transport efficiency. Here we unve…
Real and imaginary energy gaps: a comparison between single excitation Superradiance and Superconductivity and robustness to disorder
Nahum C. Chavez, Francesco Mattiotti, J. A. Mendez-Bermudez +2
A comparison between the single particle spectrum of the discrete Bardeen-Cooper-Schrieffer (BCS) model, used for small superconducting grains, and the spectrum of a paradigmatic m…
