Multifractality and statistical localization in the sparse Barrat-Mézard trap model
Diego Tapias, Peter Sollich
We study within a paradigmatic model for glassy dynamics, the Barrat-Mézard trap model, the effect of a nontrivial network structure in the connectivity among traps. Sparseness of…
Localization and top eigenvalue detection
Diego Tapias, Benedikt Grüger, Reimer Kühn +1
The detection of the top eigenvalue and its corresponding eigenvector in ensembles of random matrices has significant applications across various fields. An existing method, based…
Spectral properties, localization transition and multifractal eigenvectors of the Laplacian on heterogeneous networks
Jeferson D. da Silva, Diego Tapias, Peter Sollich +1
We study the spectral properties and eigenvector statistics of the Laplacian on highly-connected networks with random coupling strengths and a gamma distribution of rescaled degree…
Bringing together two paradigms of non-equilibrium: Fragile versus robust aging in driven glassy systems
Diego Tapias, Charles Marteau, Fabián Aguirre-López +1
There are two key paradigms for non-equilibrium dynamics: on the one hand, aging towards an equilibrium state that cannot be reached on reasonable timescales; on the other, externa…
