摘要
Ising-like analog spins subject to Boltzmann noise are built with electronic operational amplifiers. These units are used to model several situations in stochastic systems with a tailor-made analog computer. Among them, an experimental realization or stochastic resonance in an Ising lattice and the study of a single-site highly correlated electron system. The potentialities of analog computing to fill the gap between numerical Simulations and natural experimental systems with stochastic phenomena are highlighted.
