Nonlocal effects in the resistance of one-dimensional wires with dangling side branches

• We have studied the quantum corrections to the resistance of one-dimensional gold wires with periodically spaced dangling side branches. Both the weak localization and interaction corrections to the resistance of such samples are strongly reduced when the distance between branches becomes smaller than the quantum length scales. The dependence of the quantum corrections on the distance between the branches then becomes a measurement of the quantum lengths
