Forgetting Memories and their Attractiveness
Enzo Marinari
We study numerically the memory which forgets, introduced in 1986 by Parisi by bounding the synaptic strength, with a mechanism which avoid confusion, allows to remember the patter…
The out-equilibrium 2D Ising spin glass: almost, but not quite, a free-field theory
L. A. Fernandez, E. Marinari, V. Martin-Mayor +2
We consider the spatial correlation function of the two-dimensional Ising spin glass under out-equilibrium conditions. We pay special attention to the scaling limit reached upon ap…
An experiment-oriented analysis of 2D spin-glass dynamics: a twelve time-decades scaling study
L. A. Fernandez, E. Marinari, V. Martin-Mayor +2
Recent high precision experimental results on spin-glass films ask for a detailed understanding of the domain-growth dynamics of two-dimensional spin glasses. To achieve this goal,…
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…
Power spectral density of a single Brownian trajectory: What one can and cannot learn from it
Diego Krapf, Enzo Marinari, Ralf Metzler +3
The power spectral density (PSD) of any time-dependent stochastic processes is a meaningful feature of its spectral content. In its text-book definition, the PSD is the Fouri…
