Research
We investigate materials dominated by strong manifestations of quantum interactions that lead to novel types of ordering, topology, phase transitions or functionalities. Our scope is to study the fundamental physics of these materials with a focus on basic research, yet including the perspective on their technological relevance. Our experimental core technology is nonlinear optical spectroscopy with pulsed lasers. In addition we apply atomic force microscopy and standard magnetic and dielectric characterization methods. Furthermore, our pulsed-laser deposition facilities allow to design next-generation multifunctional thin films and heterostructures in house. Specific materials classes of interest are:
- Multiferroics, which are simultaneously (anti-) ferromagnetic, ferroelectric and ferroelastic and/or ferrotoroidic.
- Transition-metal oxides with interface states different from the bulk.
- Materials with phase transitions determined by the competition of spins, charges, lattice and strain.
- New states of matter driven by the excitation with ultrafast optical and Terahertz pulses.
- Nonlinear optical materials
- Complex oxide thin films and heterostructures growth
- Strongly correlated systems such as heavy fermions
