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