Neutron spectroscopy
Our research focuses on the study of the critical dynamics and the static properties of strongly correlated electron materials using scattering methods.
Among others our studies include systems close to quantum criticality, geometric frustration in magnetic metals, spin-density-wave and charge- density-wave compounds, unconventional superconductors, etc.

(right) Inverse lifetime of the spin fluctuations versus temperature in the normal state of CeCu2Si2. With decreasing tempeature the lifetime almost diverges as expected near a QCP.
