Towards Certifiable State Estimation under Observability Degeneracy
Baoshan Song
Certifiable optimization provides global optimality guarantees for non-convex state estimation in robotics. However, under severe physical sensing degeneracy, convex Semidefinite P…
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…
Evidence of a second-order phase transition in the six-dimensional Ising spin glass in a field
Miguel Aguilar-Janita, Victor Martin-Mayor, Javier Moreno-Gordo +1
The very existence of a phase transition for spin glasses in an external magnetic field is controversial, even in high dimensions. We carry out massive simulations of the Ising spi…
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…
Deepening the knowledge of Spin Glasses: Metastate, Off-equilibrium phenomena and Temperature Chaos
Javier Moreno-Gordo
This thesis pretends to be another step in the development of numerical research in disordered systems. Specifically, we will focus on spin glasses which have demonstrated to be a…
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…
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,…
Scaling law describes the spin-glass response in theory, experiments and simulations
Q. Zhai, I. Paga, M. Baity-Jesi +24
The correlation length , a key quantity in glassy dynamics, can now be precisely measured for spin glasses both in experiments and in simulations. However, known analysis method…
The Mpemba effect in spin glasses is a persistent memory effect
Janus collaboration, M. Baity-Jesi, E. Calore +21
The Mpemba effect occurs when a hot system cools faster than an initially colder one, when both are refrigerated in the same thermal reservoir. Using the custom built supercomputer…

Janus Collaboration, M. Baity-Jesi, E. Calore +20
Experiments on spin glasses can now make precise measurements of the exponent governing the growth of glassy domains, while our computational capabilities allow us to make q…
Numerical construction of the Aizenman-Wehr metastate
A. Billoire, L. A. Fernandez, A. Maiorano +6
Chaotic size dependence makes it extremely difficult to take the thermodynamic limit in disordered systems. Instead, the metastate, which is a distribution over thermodynamic state…
