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…

Macroscopic coherence as an emergent property in molecular nanotubes
Marco Gulli, Alessia Valzelli, Francesco Mattiotti +3
Nanotubular molecular self-aggregates are characterized by a high degree of symmetry and they are fundamental systems for light-harvesting and energy transport. While coherent effe…

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…
