Universal equilibrium distribution after a small quantum quench
Lorenzo Campos Venuti, Paolo Zanardi
A sudden change of the Hamiltonian parameter drives a quantum system out of equilibrium. For a finite-size system, expectations of observables start fluctuating in time without con…

Unitary equilibrations: probability distribution of the Loschmidt echo
Lorenzo Campos Venuti, Paolo Zanardi
Closed quantum systems evolve unitarily and therefore cannot converge in a strong sense to an equilibrium state starting out from a generic pure state. Nevertheless for large syste…
