Coupled quantum corrals
ORAL
Abstract
We investigate the properties of electronic states in quantum corrals assembled by single molecule STM manipulation. In particular, we analyze theoretically corrals with geometries similar to various aromatic molecules, such as benzene. Furthermore, we couple the benzene-like structure to multiple rectangular corrals or resonators, and investigate the effect of the resonator-benzene corral interaction on the local density of states. We find that for a certain energy and coupling range the effect of the resonator on the trapped electron states of the corral is similar to that of a local electric field. This finding opens the possibility of using resonators as gates in studying the interaction between electronic states in the corral and external quantum systems.
