摘要: We study analytically the effect of temperature cyclings in mean-field spin glasses. In accordance with real experiments, we obtain a strong reinitialization dynamics on decreasing combined memory effects when original high is restored. The same calculation applied to models structural glasses shows no such reinitialization, again experiments. this context, derive some relations between experimentally accessible quantities and propose experimental protocols. Finally, briefly discuss field during isothermal aging.
