We use photons and neutrons as probes in various scattering experiments to investigate time and space correlations in ferroelectrics and related materials. Concretely:
- dispersions of phonons, especially soft ferroelectric phonons,
- polar fluctuations in vicinity of phase transitions,
- relaxation modes in relaxor ferroelectrics,
- ferroelectric and ferroelastic domains,
- polar nanoscopic regions in disordered systems,
- domain walls and other topological defects, etc.
