The main research objective of our group is to investigate quantum effects of nano- and microscale systems and their implications for the foundations and applications of quantum physics. Our goal is to gain access to a completely new parameter regime for experimental physics with respect to both size and complexity.

Schrödingers Katze auf dem Prüfstand

What happens with the sometimes mysterious quantum physics phenomenon when watching larger and heavier objects? Already Erwin Schrödinger and Albert Einstein disputed about this. New experiments with systems of larger mass shall provide clues to solve this fundamental mystery.

Looking at quantum gravity in a mirror

Einstein’s theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale is so remote from current experimental capabilities that tests of quantum gravity are widely believed to be nearly impossible.  Now an international collaboration between the groups at the University of Vienna and at Imperial College London has proposed a new quantum experiment using Planck-mass mirrors.
