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.

Topological high-harmonic generation

Together with the groups of Klaus Richter (UR), Ferdinand Evers (UR), Ulrich Höfer (University of Marburg) and collaborators from the Novosibirsk State University, we discovered a novel generation mechanism of high-order harmonics in the surface state of a topological insulator. When quasi-relativistic electrons are accelerated through the Dirac point by an intense lightwave, they abruptly reverse their velocity allowing for purely non-integer high-harmonic generation. The lightwave-driven currents reveal intriguing aspects of the quantum mechanical nature of electrons in topological matter.

Ultrafast terahertz nanoscopy: Coverstory in Nature Photonics

In collaboration with the group of Jaroslav Fabian (UR) and together with Tyler Cocker and Jessica Boland, we implemented a novel concept to map out ultrafast interlayer tunneling and recombination dynamics of excitons in van der Waals heterostructures in a contact-free manner. The new technique provides spatiotemporal access to tunnelling processes in insulating, conducting, or superconducting systems, on nanometer length and femtosecond time scales, conceptually bridging the gap between near-field microscopy and light-wave driven STM.

Tailored Subcycle Nonlinearities of Ultrastrong Light-Matter Coupling

Together with the groups of Dominique Bougeard (UR) and Cristiano Ciuti (Université de Paris), we explored a novel regime of light-matter interaction, where both the Rabi frequency induced by a coherent driving field and the vacuum Rabi frequency set by a cavity field are comparable to the carrier frequency of light. The resulting subcycle nonlinearities may facilitate novel nonclassical light sources, quantum phase transitions, or cavity chemistry with virtual photons.

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