Query: Enhanced charge order in a photoexcited one-dimensional strongly
  correlated system   We present a compelling response of a low-dimensional strongly correlated
system to an external perturbation. Using the time-dependent Lanczos method we
investigate a nonequilibrium evolution of the half-filled one-dimensional
extended Hubbard model, driven by a transient laser pulse. When the system is
close to the phase boundary, by tuning the laser frequency and strength, a
sustainable charge order enhancement is found that is absent in the Mott
insulating phase. We analyze the conditions and investigate possible mechanisms
of emerging charge order enhancement. Feasible experimental realizations are
proposed.
