title: Transport properties of a boundary-driven one-dimensional gas of spinless fermions.
abstract: 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(-α) with the chain length n, α 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/2ξ) above the transition. Therefore, by a simple change of frequency of the a.c. driving of the system one can vary transport from ballistic, anomalous to insulating.
