Query: Multiple particle-hole pair creation in the Fermi-Hubbard model by a
  pump laser   We study the Fermi-Hubbard model in the strongly correlated Mott phase under
the influence of a harmonically oscillating electric field, e.g., a pump laser.
In the Peierls representation, this pump field can be represented as an
oscillating phase of the hopping rate $J(t)$, such that the effective
time-averaged rate $\bar J$ is reduced, i.e., switching the pump laser suddenly
is analogous to a quantum quench. Apart from this time-averaged rate $\bar J$,
it is well known that the oscillating component of $J(t)$ can resonantly create
particle-hole pairs if the pump frequency $\omega_{\rm pump}$ equals (or a
little exceeds) the Mott gap. In addition, we find that it is possible to
create multiple pairs if $\omega_{\rm pump}$ is near an integer multiple of the
gap. These findings should be relevant for pump-probe experiments.
