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.

Together with our long-term collaborators Mack Kira (University of Michigan, Ann Arbor) and Stephan W. Koch (Philipps Universität Marburg), we have developed an all-optical way of mapping out electronic band structures of even tiny flakes of quantum materials in ambient air. Our approach uses a new concept called momentum combs to achieve super-resolution, which could help us to tailor emerging quantum materials and pave the way for advanced energy technologies and quantum computers.

In close collaboration with the groups of Jascha Repp (UR) and Angel Rubio (Max Planck Institute for the Structure and Dynamics of Matter, Hamburg), we found a way to map out atom-scale lightwave dynamics. Using a single-molecule switch, which senses changes in the local electromagnetic fields, we were able to quantitatively detect atom-scale near-field waveforms in the junction of a scanning tunneling microscope.

Together with our collaborators from Jascha Repp's group and Nikolaj Moll, we have found a fascinating way to push a select atom with controlled forces so quickly that we can choreograph the motion of a single molecule within less than a trillionth of a second.

Together with the groups of Prof. Dr. Miriam S. Vitiello (Pisa) and Prof. Dr. Edmund Linfield (Leeds) we developed a new group of saturable absorbers in the terahertz spectral domain based on ultra-strong coupling of intersubband transitions to the resonant mode of a microresonator. These new devices could enable passive mode locking of future quantum cascade lasers.

In close collaboration with the group of Dominique Bougeard and with Cristiano Ciuti (Université de Paris), we managed to switch off deep-strong light-matter coupling much faster than a cycle of light. Our breakthrough provides a very unusual glimpse behind the virtual photon dress of electrons, which helps unravelling the nature of vacuum fluctuations. In the future, even chemical reactions or superconductivity may be triggered merely by abrupt modification of the quantum vacuum.
The results are reported in Nature Photonics....
