Theoretical Nanoelectronics

The quantum mechanical nature of matter is the basis of all functioning of electronic devices. We use techniques from many-body physics, from quantum statistical physics, and from the mathematics of topology, to analyze the properties of electrons in a wide range of present-day exploratory devices. Our work can enable the development of new qubits, and new approaches to building a quantum computer.

Innovations for Quantum Computing with Topological Insulators

Forschungszentrum Jülich and the University of Würzburg will together investigate the quantum phenomena of topological materials and the opportunities they present within quantum computing. The Free State of Bavaria is funding the project to the tune of € 13 million.

PGI Colloquium - Extraordinary Talk: Prof. Dr. Stephan Appelt,
Forschungszentrum Jülich (ZEA-2) and RWTH Aachen (ITMC), Germany

In this colloquium, the discussion will centre on the physics of the parahydrogen pumped RASER (Radio-frequency Amplification by Stimulated Emission of Radiation) [1], which is an ideal quantum sensor for exploring self-organized phenomena between spins and photons. RASER activity can be observed if the low-frequency photons of a high Q resonator [2] interact with a negatively polarized nuclear spin ensemble.

Electronic Properties of Nanostructured Materials

Atomic order-disorder transitions or phase transitions like freezing-melting are among the most dramatic effects occurring in condensed matter.

Quantum Information Processing

We work at the fundamental level on the theory of quantum information processing, developing new concepts for qubits and multi-qubit modules.  We work closely with the experimental scientists in PGI-11.
