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 …

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 …

Publisher Summary This introductory chapter provides a first presentation of an intellectual
framework for understanding the foundational and philosophical issues raised by the …

The study of spin-glass dynamics, long considered the paradigmatic complex system, has
reached important milestones. The availability of high-quality single crystals has allowed the …

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 …

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 …

This paper describes the architecture, the development and the implementation of Janus II, a
new generation application-driven number cruncher optimized for Monte Carlo simulations …

The correlation length ξ, a key quantity in glassy dynamics, can now be precisely measured
for spin glasses both in experiments and in simulations. However, known analysis methods …

Experiments on spin glasses can now make precise measurements of the exponent z (T)
governing the growth of glassy domains, while our computational capabilities allow us to …

We present a massive equilibrium simulation of the three-dimensional Ising spin glass at low
temperatures. The Janus special-purpose computer has allowed us to equilibrate, using …
