Huber group


Welcome to the Huber group at the University of Regensburg!

Many of the fundamental laws and unexpected phenomena in condensed matter physics are caused by extremely fast dynamics of electrons and ions on the femtosecond time (1 fs = 10-15 s) and terahertz frequency scale (1 THz = 1012 Hz). Unravelling such ultrafast processes is the main interest of our research. We develop next-generation, high-intensity femtosecond laser sources and THz technology, and employ them to explore novel femtophysics.

Generating intense sub-half-cycle terahertz pulses

We developed a novel, flexible and scalable emitter of extremely asymmetric and intense terahertz field transients together with the groups of Dominique Bougeard (UR) and Mackillo Kira (University of Michigan) as well as collaborators from the Helmut Schmidt University and the Justus Liebig University Gießen. Making use of shift currents and local charging dynamics in asymmetrically coupled epitaxial semiconductor heterostructures, we generated waveforms exhibiting less than an oscillation half-cycle, peak fields above 1.1 kV cm-1 and spectra spanning into the mid-infrared, marking a milestone for next-generation high-repetition-rate (multi-)terahertz sources.
