How to increase a transmission with weak localization ? A geometrical effect
Christophe Texier, Gilles Montambaux
Abstract
We study the quantum transport in multiterminal networks of quasi-one-dimensional diffusive wires. When calculating the weak localization correction to the conductances, we show that the Cooperon must be properly weighted over each wire. This can even change the sign of the weak localization correction in certain geometries.
