Spin-glass dynamics: experiment, theory and simulation
E. D. Dahlberg, I. González-Adalid Pemartín, E. Marinari +8
The study of spin-glass dynamics, long considered the paradigmatic complex system, has reached important milestones. The availability of single crystals has allowed the experimenta…
Daydreaming Hopfield Networks and their surprising effectiveness on correlated data
Ludovica Serricchio, Dario Bocchi, Claudio Chilin +4
To improve the storage capacity of the Hopfield model, we develop a version of the dreaming algorithm that perpetually reinforces the patterns to be stored (as in the Hebb rule), a…
Small field chaos in spin glasses: universal predictions from the ultrametric tree and comparison with numerical simulations
Miguel Aguilar-Janita, Silvio Franz, Victor Martin-Mayor +4
We study the chaotic behavior of the Gibbs state of spin-glasses under the application of an external magnetic field, in the crossover region where the field intensity scales propo…
Multifractality in spin glasses
Janus Collaboration, M. Baity-Jesi, E. Calore +21
We unveil the multifractal behavior of Ising spin glasses in their low-temperature phase. Using the Janus II custom-built supercomputer, the spin-glass correlation function is stud…
Spin-glass dynamics in the presence of a magnetic field: exploration of microscopic properties
I. Paga, Q. Zhai, M. Baity-Jesi +24
The synergy between experiment, theory, and simulations enables a microscopic analysis of spin-glass dynamics in a magnetic field in the vicinity of and below the spin-glass transi…
Dynamic Variational Study of Chaos: Spin Glasses in Three Dimensions
A. Billoire, L. A. Fernandez, A. Maiorano +6
We have introduced a variational method to improve the computation of integrated correlation times in the Parallel Tempering Dynamics, obtaining a better estimate (a lower bound, a…
Dynamical transition in the D = 3 Edwards-Anderson spin glass in an external magnetic field
Janus Collaboration, M. Baity-Jesi, R. Alvarez Baños +22
We study the off-equilibrium dynamics of the three-dimensional Ising spin glass in the presence of an external magnetic field. We have performed simulations both at fixed temperatu…
Reconfigurable computing for Monte Carlo simulations: results and prospects of the Janus project
Janus Collaboration, M. Baity-Jesi, R. A. Banos +24
We describe Janus, a massively parallel FPGA-based computer optimized for the simulation of spin glasses, theoretical models for the behavior of glassy materials. FPGAs (as compare…
