  The generic non-equilibrium evolution of a strongly interacting fermionic
system is studied. For strong quenches, a collective collapse-and-revival
phenomenon is found extending over the whole Brillouin zone. A qualitatively
distinct behavior occurs for weak quenches where only weak wiggling occurs.
Surprisingly, no evidence for prethermalization is found in the weak coupling
regime. In both regimes, indications for relaxation beyond oscillatory or power
law behavior are found and used to estimate relaxation rates without resorting
to a probabilistic ansatz. The relaxation appears to be fastest for
intermediate values of the quenched interaction.
