Large scale simulations of photosynthetic antenna systems: interplay of cooperativity and disorder
Alessia Valzelli, Alice Boschetti, Francesco Mattiotti +4
Large scale simulations of light-matter interaction in natural photosynthetic antenna complexes containing more than one hundred thousands chlorophyll molecules, comparable with na…
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.…
Enhanced robustness and dimensional crossover of superradiance in cuboidal nanocrystal superlattices
Sushrut Ghonge, David Engel, Francesco Mattiotti +3
Cooperative emission of coherent radiation from multiple emitters (known as superradiance) has been predicted and observed in various physical systems, most recently in CsPbBr…
Engineering random spin models with atoms in a high-finesse cavity
Nick Sauerwein, Francesca Orsi, Philipp Uhrich +6
All-to-all interacting, disordered quantum many-body models have a wide range of applications across disciplines, from spin glasses in condensed-matter physics, over holographic du…
Efficient light harvesting and photon sensing via engineered cooperative effects
Francesco Mattiotti, Mohan Sarovar, Giulio G. Giusteri +2
Efficient devices for light harvesting and photon sensing are fundamental building blocks of basic energy science and many essential technologies. Recent efforts have turned to bio…
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…
Bio-inspired natural sunlight-pumped lasers
Francesco Mattiotti, William M. Brown, Nicola Piovella +3
Even though sunlight is by far the most abundant renewable energy source available to humanity, its dilute and variable nature has kept efficient ways to collect, store, and distri…
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…
Localization of light in three dimensions: a mobility edge in the imaginary axis in non-Hermitian Hamiltonians
Giuseppe Luca Celardo, Mattia Angeli, Francesco Mattiotti +1
Searching for Anderson localization of light in three dimensions has challenged experimental and theoretical research for the last decades. Here the problem is analyzed through lar…
Temperature of a single chaotic eigenstate
Fausto Borgonovi, Francesco Mattiotti, Felix M. Izrailev
The onset of thermalization in a closed finite system of randomly interacting bosons, at the level of a single eigenstate, is discussed. The main interest is in the emergence of th…
Non-Hermitian Hamiltonian approach to quantum transport in disordered networks with sinks: validity and effectiveness
Giulio G. Giusteri, Francesco Mattiotti, G. Luca Celardo
We investigate the validity of the non-Hermitian Hamiltonian approach in describing quantum transport in disordered tight-binding networks connected to external environments, actin…
