Abstract:
The control of quantum transport is an issue of current interest for constructing new devices. In this work, we investigate this possibility in quantum graphs. The study allows the identification of two distinct periodic quantum effects, one being the identification of transport inefficiency and the other the presence of peaks of full transmission inside regions of suppression of transport in some elementary graphs. Motivated by the power of quantum graphs, we elaborate on the construction of simple devices based on microwave and optical fiber networks and quantum dots, nanowires, and nanorings. The elementary devices can be used to construct composed structures with important quantum properties, which may be used to manipulate the quantum transport.
