  We study the non-equilibrium dynamics of one-dimensional Mott insulating
bosons in the presence of a tunable effective electric field E which takes the
system across a quantum critical point (QCP) separating a disordered and a
translation symmetry broken ordered phase. We provide an exact numerical
computation of the residual energy Q, the log-fidelity F, the excess defect
density D, and the order parameter correlation function for a linear-in-time
variation of E with a rate v. We discuss the temporal and spatial variation of
these quantities for a range of v and for finite system sizes as relevant to
realistic experimental setups [J. Simon et al., Nature 472, 307 (2011)]. We
show that in finite-sized systems Q, F, and D obey Kibble-Zurek scaling, and
suggest further experiments within this setup to test our theory.
