We are looking for candidates who want to pursue a theoretical PhD in Optomechanics and low energy Quantum gravity.  The selected applicant will investigate optically levitated systems in situations, where gravitational interactions become important.  This research project offers the possibility to, on the one hand, be close to state of the art experiments, while on the other hand,   explore theoretically the elusive relationship between quantum mechanics and gravity.

The PhD research project will focus on developing proposals for testing gravitational interactions in optomechanical experiments. These experiments, which are already exploring the quantum-to-classical transition, offer a realistic possibility of  also testing gravitational interaction in a quantum mechanical regime, using a relatively simple table-top setup.  Moreover, rival theories, such as modified theories of gravity and gravity-based quantum spontaneous collapse models, could also be tested. The modelling of the post-Newtonian and non-unitary corrections to the dynamics will incorporate methods from General relativity as well as from Open quantum theory.  Particular emphasis will be given to Quantum gravity phenomenology that is testable with current experiments in the near future.

Applicants should possess a MSc Physics and have a good background in theoretical physics. Previous experience in General relativity, Open quantum theory, and Optomechanics will be an advantage. Other highly motivated candidates will also be considered and are encouraged to apply.

The successful candidate will conduct research under the supervision of Prof. Hendrik Ulbricht in the Quantum Light and Matter group at the University of Southampton. The selected applicant will also take part in collaborations with researches from other Universities. For further enquiries write to h.ulbricht@soton.ac.uk.
