Evidence of de Almeida-Thouless line below six dimensions
M. Aguilar-Janita, V. Martin-Mayor, J. Moreno-Gordo +1
We study the critical behavior of the Ising spin glass in five spatial dimensions through large-scale Monte Carlo simulations and finite-size scaling analysis. Numerical evidence f…
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…
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…
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…
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…
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…
Effective and asymptotic criticality of structurally disordered magnets
Maxym Dudka, Mariana Krasnytska, Juan J. Ruiz-Lorenzo +1
Changes in magnetic critical behaviour of quenched structurally-disordered magnets are usually exemplified in experiments and in MC simulations by diluted systems consisting of mag…
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…
Critical Behavior of the Three-Dimensional Random Anisotropy Heisenberg Model
J. J. Ruiz-Lorenzo, M. Dudka, Yu. Holovatch
We have studied the critical properties of the three-dimensional random anisotropy Heisenberg model by means of numerical simulations using the Parallel Tempering method. We have s…
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…
How we are leading a 3-XORSAT challenge: from the energy landscape to the algorithm and its efficient implementation on GPUs
M. Bernaschi, M. Bisson, M. Fatica +4
A recent 3-XORSAT challenge required to minimize a very complex and rough energy function, typical of glassy models with a random first order transition and a golf course like ener…
Spin-glass dynamics in the presence of a magnetic field: exploration of microscopic properties

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…
Temperature chaos is present in off-equilibrium spin-glass dynamics
Janus Collaboration, M. Baity-Jesi, E. Calore +22
We find a dynamic effect in the non-equilibrium dynamics of a spin glass that closely parallels equilibrium temperature chaos. This effect, that we name dynamic temperature chaos,…
Transition between anomalous and Anderson localization in systems with non-diagonal disorder driven by time-periodic fields
Rafael A. Molina, Victor A. Gopar
In models of hopping disorder in the absence of external fields and at the band center, the electrons are less localized in space than the standard exponential Anderson localizatio…

Q. Zhai, V. Martin-Mayor, D. L. Schlagel +2
The growth of the spin-glass correlation length has been measured as a function of the waiting time on a single crystal of CuMn (6 at.\%), reaching values $ξ\sim 1…
Strong ergodicity breaking in aging of mean field spin glasses
Massimo Bernaschi, Alain Billoire, Andrea Maiorano +2
Out of equilibrium relaxation processes show aging if they become slower as time passes. Aging processes are ubiquitous and play a fundamental role in the physics of glasses and sp…
