- Extreme Quanten-Materie im Festkörper
The collective excitations of solids at very low excitation energies may be described as particle-like states. Important examples are phonons, magnons or plasmons. However, increasing evidence suggests a dominant role of subtle stochastic processes and that proper account of the full spectrum of fluctuations yields the key for many of the most puzzling materials properties reported in the recent literature. Ultra-high resolution neutron spectroscopy provides deep insights on the nature and the consequences of these subtle fluctuations, in particular the emergence of entangled quantum matter.
The proposed project pursues measurements of stochastic processes of extreme quantum matter in solids with ultra-high energy resolution by means of neutron resonance spin-echo spectroscopy. In recent years we have implemented a new and extremely powerful variant of this technique at FRM II. The experiments range from technical developments of the neutron beam-line RESEDA at FRM II, the experimental studies, analysis of the data and complementary measurements using other neutron scattering techniques as well as laboratory based methods, where suitable.
