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.

Intersubband Polariton-Polariton Scattering

We studied the ultrafast dynamics of intersubband polaritons in the mid-infrared together with the groups of Raffaele Colombelli (Paris), Christoph Lange (Dortmund) and Iacopo Carusotto (Trento). Stimulated scattering occurs between these polaritons for resonant excitation, which we observe directly within the polaritonic bandstructure. This scattering mechanism could enable Bose-Einstein-condensates of intersubband polaritons for novel quantum computers and on-chip mid-infrared light sources.

The results have been published in Physical Review Letters.... more

Light-field-driven tunneling currents in a Schottky diode

In collaboration with the group of Heiko Weber (Friedrich-Alexander-Universität Erlangen-Nürnberg) we investigated mid-infrared light-field-driven tunneling currents in a Schottky diode, consisting of epitaxial graphene on silicon carbide. Our study gives insights into the intrinsic speed limits of rectification currents in these devices and paves the way towards light-field-driven electronics with increased functionality, such as transistors and logic circuits.

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.
