Topological quantum phenomena in low dimensional systems

New and interesting quantum phenomena can occur when particles are confined to one or two dimensions. This can happen in anisotropic materials, cold atomic gases and in microelectronic devices.

Especially interesting are phenomena where the "standard" theory of electron behavior breaks down because of large quantum fluctuations or interactions.  Recently it has been suggested that topology can play a role in the description of the ground state and excitations in such systems. These are exciting possibilities which will be pursued in parts of this project.

The discovery of unconventional states of materials has often come as surprises, and probably there are more to come. The intention of this project is to extend the understanding of interacting particles in low dimensional systems in order to predict and to increase the usefulness of recent and future discoveries. A solid physical understanding of the underlying physics is an important prerequisite for future technological applications based on such discoveries.




About the project


This is a basic research project in theoretical physics, where the goal is to extend the understanding of fundamental quantum phenomena in low dimensional systems.


The Research council of Norway in collaboration with the University of Oslo (2012-2016)

Principal investigators

The project is a collaboration between Prof. Jon Magne Leinaas, Prof. Olav Syljuåsen and Prof. Susanne Viefers (Project leader)
