Resumen:
We study the statistics of the work done, fluctuation relations, and
irreversible entropy production in a quantum many-body system subject to
the sudden quench of a control parameter. By treating the quench as a
thermodynamic transformation we show that the emergence of
irreversibility in the nonequilibrium dynamics of closed many-body
quantum systems can be accurately characterized. We demonstrate our
ideas by considering a transverse quantum Ising model that is taken out
of equilibrium by an instantaneous change of the transverse field.
