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…
An Introduction to the Theory of Spin Glasses
Ada Altieri, Marco Baity-Jesi
We review the main methods used to study spin glasses. In the first part, we focus on methods for fully connected models and systems defined on a tree, such as the replica method,…
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,…
Precursors of the Spin Glass Transition in Three Dimensions
Marco Baity-Jesi, Victor Martin-Mayor
We study energy landscape and dynamics of the three-dimensional Heisenberg Spin Glass model in the paramagnetic phase, i.e. for temperature larger than the critical temperature…
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…
Aging rate of spin glasses from simulations matches experiments
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…
Matching microscopic and macroscopic responses in glasses
Janus Collaboration, M. Baity-Jesi, E. Calore +20
We first reproduce on the Janus and Janus II computers a milestone experiment that measures the spin-glass coherence length through the lowering of free-energy barriers induced by…
A statics-dynamics equivalence through the fluctuation-dissipation ratio provides a window into the spin-glass phase from nonequilibrium measurements
Janus Collaboration, M. Baity-Jesi, E. Calore +20
The unifying feature of glass formers (such as polymers, supercooled liquids, colloids, granulars, spin glasses, superconductors, ...) is a sluggish dynamics at low temperatures. I…
Criticality and Energy Landscapes in Spin Glasses
Marco Baity-Jesi
Despite the extreme simplicity in their definition, spin glasses disclose a wide variety of non-trivial behaviors that are not yet fully understood. In this thesis we try to shed l…
Soft Modes, Localization and Two-Level Systems in Spin Glasses
Marco Baity-Jesi, Victor Martin-Mayor, Giorgio Parisi +1
In the three-dimensional Heisenberg spin glass in a random field we study the properties of the inherent structures that are obtained by an instantaneous cooling from infinite temp…
Energy landscape in three-dimensional Heisenberg spin glasses
Marco Baity-Jesi
Recent work suggests that Heisenberg spin glasses may belong to the same universality class than structural glasses. Indeed, finding a lattice equivalent for supercooled liquids wo…
Critical parameters of the three-dimensional Ising spin glass
Janus Collaboration, M. Baity-Jesi, R. A. Baños +22
We report a high-precision finite-size scaling study of the critical behavior of the three-dimensional Ising Edwards-Anderson model (the Ising spin glass). We have thermalized latt…
