The main goal of our work is devoted to explore non-classical properties such as superposition and entanglement of massive particles at mesoscopic scales. Our core business is matter-wave interferometry experiments with heavy molecules and nanoparticles. Such experiments hold promise to test possible limitations of quantum theory.
We are always looking for interested and talented post-docs. If you are interested and for more details please contact Dr Hendrik Ulbricht (h.ulbricht[at]soton.ac.uk).Current research projects include:
We run a Talbot-Lau Interferometer to perform quantum superposition experiments with molecules in the mass range of up to 10.000 amu (atomic mass units).
Molecular beam techniques
We use optical and magnetic fields to manipulate and focus the centre of mass motion of molecules as well as Neon buffer gas techniques to cool molecular degrees of freedom.
We combine Talbot-Lau interferometry with optical tweezing and guiding techniques of 10nm to 100nm bead particles to demonstrate spatial quantum superposition. Experiments in this parameter range can test collapse models to extend quantum theory.
Graphene quantum optics
We use nanofabrication techniques to build membrane based particle detectors as well as electron transport devices to implement electron quantum optics ideas.
