Abstract
A simple but quite non-trivial class of non-equilibrium processes of a quantum many-body system is quantum quenches. We start with a ground state \(\mid \!\Phi _{0}\rangle\) of a certain Hamiltonian H 0. At time tâ=â0, we suddenly change the Hamiltonian from H 0 to a new one H. The original state \(\mid \!\Phi _{0}\rangle\) no longer stays at the ground state and starts to experience the time evolution for tâ>â0. Such a process is called a quantum quench. In particular, when the Hamiltonian changes homogeneously over the whole space, it is called a global quench [131, 132, 133], while if the change is localized in a certain small region, it is called a local quench [134].

This illustrates an important fact: while the overall spatial volume inside a black hole shrinks to zero, areas of spatial sections actually continue to grow. This has been conjectured to be related to the growth of complexity of the state [157].
