A characteristic feature of the non-equilibrium dynamics of real spin glasses at low temperatures are strong aging effects. These phenomena can be manipulated by changing the external parameters in various ways: a thermo-cycling experiment consists for instance of a short heat pulse during the waiting time, by which the relaxation might be strongly affected. Results of numerical experiments of this kind, performed via Monte Carlo simulations of the threedimensional Ising spin glass model, are presented. The theoretical implications are discussed and the scenario found is compared with the experimental situation.
