Statistics of observables
and universal behaviour in quantum quenches and dynamical phase transitions.
The study of the dynamics of
thermally isolated many-body systems offers a unique opportunity to
address the role of
universality in non equilibrium quantum phenomena.
In this talk I will discuss
recent results concerning the statistics of the work and of other observables
in spin chains and bosonic
systems out of equilibrium. I will show that the statistics of the work
at low energies for spin
chains (or bosonic systems) subject to a generic local or global variation
of the transverse field is
independent on the detail of the protocol, an example of
universal behaviour both in
time and space. I will similarly show that the statistics of excitations
can be used to discuss
universality and detect efficiently dynamical phase transitions.
