Superconductor -- quantum-Hall systems
Abstract
In a superconductorÐquantum-Hall (SC-QH) structure a superconductor is placed in close proximity to a system in the quantum Hall (QH) regime. These structures are a new class of condensed matter systems for which currently little is known. The objective of this project is to fill the current gap in the theoretical understanding of these systems. This objective will be achieved using a combination of analytical and computational approaches. Numerically and diagrammatic techniques will be used to obtain the transport properties of SC-QH systems. It has been suggested that some types of SC-QH structures can be engineered to realize non-abelian electronic states such as Majoranas and parafermions. These states are of great fundamental interest and, in addition, due to their non-abelian nature, can be exploited to realize a Òtopological quantum computerÓ, i.e. a fault-tolerant quantum computer. The type of SC-QH structures that are expected to be able to support non-abelian electronic states will be studied within the theoretical framework that will be created to describe general SC-QH structures. The outcome of the project should advance our understanding of SC-QH systems, contribute toward the realization of novel non- abelian electronic states, and therefore toward the worldwide effort to realize a fault-tolerant quantum computer.
