Shot noise free conductance reduction in quantum wires
arXiv:cond-mat/0506455 · doi:10.1103/PhysRevB.74.125309
Abstract
We show that a shot noise free current at conductance below 2 e^2/h is possible in short interacting quantum wires without spin-polarization. Our calculation is done for two exactly solvable limits of the ``Coulomb Tonks gas'', a one-dimensional gas of impenetrable electrons that can be realized in ultra-thin quantum wires. In both cases we find that charge transport through such a wire is noiseless at zero temperature while the conductance is reduced to e^2/h.
