size=4>In this talk we will discuss quantum quenches, that is relaxation
properties <BR>of closed quantum systems after an external control parameter
(for exemple a <BR>magnetic field) has suddenly been changed from a given value
to a new one <BR>within a timescale much shorter than system relaxation times.
Examples of <BR>relaxation of exactly solvable models will be given.
