Controlling collective states

In this topic, researchers are investigating collective states in condensed matter, such as quantum magnetism, superconductivity, and ferroelectricity. These phenomena of spontaneous order in crystal and spin lattices, with their special properties such as quantum coherence or unusual quasiparticles, have potential for IT and energy technologies.

HZB researchers are investigating phase transitions, sometimes under extreme conditions, and new classes of materials such as multiferroic systems and unconventional superconductors, in order to understand the ordering phenomena on the atomic scale. In particular systems with suppressed order and high entropy promise interesting new properties.

Research goal

To control such states and phase transitions and to adapt them for future applications.


Crystal growth, neutron and X-ray spectroscopies, time resolved diffraction
