Current and information in the microcanonical picture of nanoscale transport



We explore fundamental physical limits to the encoding of information in a nanoscale conductor by application of electrode bias in a model electrode-conductor-electrode system. Using a microcanonical description of an atom wire bridging two electrodes, we obtain upper bounds on the accessible information in the conductor as a function of electrode bias when the current flow is governed by the conductance quantum.
