The Quantum Nanophysics Group
The Quantum Nanophysics Group (QNP) was nucleated in 2001 with the FWF START prize awarded to Markus Arndt and it was formally consolidated when Markus was appointed Ao. Prof. (2002), V-Prof. (2004) and Univ. Prof. (2008) at the University of Vienna. We have
- We started from the desire to understand the limits of quantum physics and its interface to the classical world by demonstrating quantum interference with increasingly complex and mass objects.
- We have added the exploration of a rich interface to the chemical and biomolecular sciences, developing molecular beam and detection techniques for biomolecular targets in quantum experiments.
- We have combined both in quantum enhanced measurements of complex molecular properties.
- We have added the optomechanical control and readout of translation and rotation of silicon nanoparticles up to 1010 amu, targeting quantum physics at high masses, with relevance to tests of the linearity of quantum mechanics.
All this is outlined here and throughout this entire web site.
The Beginnings of Macro-Molecular Quantum Optics
Quantum optics with complex molecules started actually even earlier, when Markus Arndt joined Anton Zeilinger's group as a postdoc at the University of Innsbruck in 1997. Together they planned and implemented the
- First C60 fullerene diffraction experiments, also together with Olaf Nairz, Julian Voss Andreae, Claudia Keller and Gerbrand van der Zouw at the University of Vienna in 1999.
The plethora of challenges and opportunities in this new research field inspired many ideas and projects, co-led by Anton and Markus (SFB F1505, 1999). Together and with a changing team of excellent young researchers, they realized the
