Quantum Theory of Materials

We calculate and analyse the complex structural, electronic, magnetic and transport quantities of quantum materials — for fundamental research and practical applications.

Can Lasers Speed Up Computers?

Only a single laser pulse is theoretically needed to reverse the magnetisation of an elementary ferromagnet. This was demonstrated by junior researcher Hanan Hamamera during her doctoral thesis at Forschungszentrum Jülich and RWTH Aachen University. This "optical switching" is a promising way to store data ultra-fast by means of laser light. Until now, up to several hundred laser pulses have been routinely needed for such a single switching process.

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.
