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 highly motivated and talented PhD students and post-docs. If you are interested and for more details please contact Prof Hendrik Ulbricht (h.ulbricht[at]soton.ac.uk).Current research projects include:
We run a Talbot-Lau Interferometer to perform quantum superposition experiments with atoms and 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 atoms and molecules.
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 which may limit quantum mechanics.
Graphene quantum optics
We use nanofabrication techniques to build electron transport devices to implement electron quantum optics ideas.
