The idea of equilibration is ubiquitous throughout nature. Out-of-equilibrium dynamics – be it caused by a disturbance and subsequent “rethermalisation”, or by passing through a phase transition – is a difficult question to characterise. This project looks at both equilibration and phase transitions in a Bose-Einstein condensate of metastable helium atoms.

For quantum technologies to transition to real-world applications, there are a multitude of engineering challenges to be solved. Using diamond NV centres, our group is developing small-scale quantum computers, and quantum microscopes sensing electric and magnetic fields down to the nanoscale. Available project themes include instrumentation, experiment control, machine learning, and optimal control.

We create the coldest stuff in the Universe – a Bose-Einstein condensate (BEC) – by laser-cooling helium atoms to within a millionth of a degree Kelvin. At these extremely low temperatures particles behave more like waves.  You will use the BEC to study fundamental quantum mechanics and for applications like atom interferometry.

An optical quantum memory will capture a pulse of light, store it and then controllably release it. This has to be done without ever knowing what you have stored, because a measurement will collapse the quantum state. We are exploring a "photon echo" process to achieve this goal.
