Research 

Many elementary excitations lie in the THz range (1THz = 4.1meV). Our goal is to probe, modify or even drive these excitations — ultrafast.

We use THz spectroscopy to study the orbital and spin dynamics of electrons in solids, liquids, and gases.
Solids of interest exhibit complex electronic behavior, for example ferromagnetism or ferroelectricity.
