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…
Multiscaling in the 3D critical site-diluted Ising ferromagnet
E. Marinari, V. Martin-Mayor, G. Parisi +2
We have studied numerically the appearance of multiscaling behavior in the three-dimensional ferromagnetic Ising site diluted model, in the form of a multifractal distribution of t…
Quantifying memory in spin glasses
Janus Collaboration, I. Paga, J. He +24
Rejuvenation and memory, long considered the distinguishing features of spin glasses, have recently been proven to result from the growth of multiple length scales. This insight, e…
Memory and rejuvenation in spin glasses: aging systems are ruled by more than one length scale
Janus Collaboration, M. Baity-Jesi, E. Calore +22
Memory and rejuvenation effects in the magnetic response of off-equilibrium spin glasses have been widely regarded as the doorway into the experimental exploration of ultrametricit…
On the superposition principle and non-linear response in spin glasses
I. Paga, Q. Zhai, M. Baity-Jesi +25
The extended principle of superposition has been a touchstone of spin glass dynamics for almost thirty years. The Uppsala group has demonstrated its validity for the metallic spin…
Numerical test of the replica-symmetric Hamiltonian for the correlations of the critical state of spin glasses in a field
L. A. Fernandez, I. Gonzalez-Adalid Pemartin, V. Martin-Mayor +5
A growing body of evidence indicates that the sluggish low-temperature dynamics of glass formers (e.g. supercooled liquids, colloids or spin glasses) is due to a growing correlatio…
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…
The three dimensional Ising spin glass in an external magnetic field: the role of the silent majority
Janus Collaboration, M. Baity-Jesi, R. A. Banos +22
We perform equilibrium parallel-tempering simulations of the 3D Ising Edwards-Anderson spin glass in a field. A traditional analysis shows no signs of a phase transition. Yet, we e…
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…
Static versus dynamic heterogeneities in the D = 3 Edwards-Anderson-Ising spin glass
Janus Collaboration, R. Alvarez Banos, A. Cruz +19
We numerically study the aging properties of the dynamical heterogeneities in the Ising spin glass. We find that a phase transition takes place during the aging process. Statics-dy…
