Query: Coherent quench dynamics in the one-dimensional Fermi-Hubbard model   Recently, it has been shown that the momentum distribution of a metallic
state of fermionic atoms in a lattice Fermi-Bose mixture exhibits coherent
oscillations after a global quench that suppresses tunneling. The oscillation
period is determined by the Fermi-Bose interaction strength. Here we show that
similar dynamics occurs in the fermionic Hubbard model when we quench a
noninteracting metallic state by introducing a Hubbard interaction and
suppressing tunneling. The period is determined primarily by the interaction
strength. Conversely, we show that one can accurately determine the Hubbard
interaction strength from the oscillation period, taking into account
corrections from any small residual tunneling present in the final Hamiltonian.
Such residual tunneling shortens the period and damps the oscillations, the
latter being visible in the Fermi-Bose experiment.
