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.

A lightning-fast atomic hand

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.

The results have been published in Nature.... more

Bleaching the blur

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.

Behind the veil of nothingness: Coverstory in Nature Photonics

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.... more

Twist-tailoring Coulomb correlations

In a collaboration with the groups of Ermin Malic, John Lupton, and Janina Maultzsch, we resolved the internal atom-like structure of excitons in a stack of two atomically thin monolayers of WSe2. Merely by changing the stacking angle, we find a drastic renormalization of the binding energy and lifetime as well as a highly tunable exciton-exciton interaction. These results pave the way for tailoring novel phases of matter in a broad range of van der Waals heterostructures.

Full Professorship for Christoph Lange at TU Dortmund!

Congratulations to Christoph Lange who has just started a new chair entitled "THz spectroscopy" at the Technische Universität Dortmund, beginning April 1, 2020. In his new group, Christoph will pursue new directions of THz cavity quantum electrodynamics on the subcycle scale. We wish him all the best for a successful start and look forward to continuing our successful collaboration!... more
