Query: Transport properties of a boundary-driven one-dimensional gas of
  spinless fermions   We analytically study a system of spinless fermions driven at the boundary
with an oscillating chemical potential. Various transport regimes can be
observed: at zero driving frequency the particle current through the system is
independent of the system's length; at the phase-transition frequency, being
equal to the bandwidth, the current decays as n^{-alpha} with the chain length
n, alpha being either 2 or 3; below the transition the scaling of the current
is n^{-1/2}, indicating anomalous transport, while it is exponentially small
exp{(-n/2xi)} above the transition. Therefore, by a simple change of frequency
of the a.c. driving one can vary transport from ballistic, anomalous, to
insulating.
