A. Oguri et H. Ishii, TRANSPORT THROUGH A SMALL INTERACTING REGION WITH A SINGLE QUANTUM LEVEL, Czechoslovak journal of Physics, 46, 1996, pp. 2411-2412
Transport through a small interacting region is studied using the quan
tum Monte Carlo method. We show an improved estimation for the conduct
ance in a single-level case. The analysis used here is applicable to t
he cases in which a number of quantum levels exist in the interaction
region.
