| contents | This thesis is devoted to the study of physical systems embedded within the field of non-equilibrium statistical mechanics. Specifically, the state of the systems of interest constitutes a stochastic process that can be externally driven by a set of controllable parameters. On the one hand, for systems in contact with a thermal bath, we have studied the emergence of strong memory effects and glassy behaviour upon varying the bath temperature, and how these are related to the existence of non-equilibrium attractors governing the dynamics. On the other hand, for overdamped harmonic systems, we have studied the problem of minimising the connection time between arbitrary stationary (either equilibrium or non-equilibrium) states, by suitably varying either the bath temperature or the stiffnesses of the potential. |
