    "abstract": "We study the dynamics of many atoms in the recently proposed Single Atom\nTransistor setup [A. Micheli, A. J. Daley, D. Jaksch, and P. Zoller, Phys. Rev.\nLett. 93, 140408 (2004)] using recently developed numerical methods. In this\nsetup, a localised spin 1/2 impurity is used to switch the transport of atoms\nin a 1D optical lattice: in one state the impurity is transparent to probe\natoms, but in the other acts as a single atom mirror. We calculate\ntime-dependent currents for bosons passing the impurity atom, and find\ninteresting many body effects. These include substantially different transport\nproperties for bosons in the strongly interacting (Tonks) regime when compared\nwith fermions, and an unexpected decrease in the current when weakly\ninteracting probe atoms are initially accelerated to a non-zero mean momentum.\nWe also provide more insight into the application of our numerical methods to\nthis system, and discuss open questions about the currents approached by the\nsystem on long timescales.",
