Nonlinear dielectric response in glasses: restoring forces and avoided spin-glass criticality
Eric Bertin, François Ladieu
Experimental measurements of nonlinear dielectric response in glassformers like supercooled glycerol or propylene carbonate have been interpreted as providing evidence for a growin…
Duality in power-law localization in disordered one-dimensional systems
X. Deng, V. E. Kravtsov, G. V. Shlyapnikov +1
The transport of excitations between pinned particles in many physical systems may be mapped to single-particle models with power-law hopping, . For randomly spaced particle…
Time delay matrix at the spectrum edge and the minimal chaotic cavities
Adel Abbout
Using the concept of minimal chaotic cavities, we give the distribution of the proper delay times of at the spectrum edge with a…
Dynamic Correlation Length Growth in Superspin Glass: Bridging Experiments and Simulations
Sawako Nakamae, Caroline Crauste-Thibierge, Denis L'Hote +4
Interacting magnetic nanoparticles display a wide variety of magnetic behaviors that are now being gathered in the emerging field of 'supermagnetism.' We have investigated how the…
Experimental Evidence of Fluctuation-Dissipation Theorem Violation in a Superspin Glass
Katsuyoshi Komatsu, D. L'Hote, Sawako Nakamae +5
We present the experimental observation of the fluctuation-dissipation theorem (FDT) violation in an assembly of interacting magnetic nanoparticles in the low temperature superspin…
Real spin glasses relax slowly in the shade of hierarchical trees
Eric Vincent, J. Hammann, Miguel Ocio
The Parisi solution of the mean-field spin glass has been widely accepted and celebrated. Its marginal stability in 3d and its complexity however raised the question of its relevan…
