Description
Interaction quenches are usually associated with heating of isolated quantum system. However, starting from non-zero temperature interaction quenches can also cool quantum systems. This is shown explicitly for the 1d Hubbard model using numerical methods, perturbative analytical methods and Bethe ansatz results. Depending on the parameter regime cooling can occur on prethermal time scales or even in the long-time limit.
