Fluctuation driven transitions in localized insulators: Intermittent metallicity and path chaos precede delocalization
Valentina Ros, Markus Müller
We study how interacting localized degrees of freedom are affected by slow thermal fluctuations that change the effective local disorder. We compute the time-averaged (annealed) co…
Distribution of rare saddles in the -spin energy landscape
Valentina Ros
We compute the statistical distribution of index-1 saddles surrounding a given local minimum of the -spin energy landscape, as a function of their distance to the minimum in con…
Anderson transition on the Bethe lattice: an approach with real energies
Giorgio Parisi, Saverio Pascazio, Francesca Pietracaprina +2
We study the Anderson model on the Bethe lattice by working directly with propagators at real energies . We introduce a novel criterion for the localization-delocalization trans…
Complex energy landscapes in spiked-tensor and simple glassy models: ruggedness, arrangements of local minima and phase transitions
Valentina Ros, Gerard Ben Arous, Giulio Biroli +1
We study rough high-dimensional landscapes in which an increasingly stronger preference for a given configuration emerges. Such energy landscapes arise in glass physics and inferen…
