abstract = {We measure the ultrafast recombination of photoexcited
quasiparticles (holon-doublon pairs) in the one dimensional
Mott insulator ET–F$_2$TCNQ as a function of external
pressure, which is used to tune the electronic structure. At
each pressure value, we first fit the static optical
properties and extract the electronic bandwidth t and the
intersite correlation energy V. We then measure the
recombination times as a function of pressure, and we
correlate them with the corresponding microscopic
parameters. We find that the recombination times scale
differently than for metals and semiconductors. A fit to our
data based on the time-dependent extended Hubbard
Hamiltonian suggests that the competition between local
recombination and delocalization of the Mott-Hubbard exciton
dictates the efficiency of the recombination.},
