Shining new light on the ‘proton radius puzzle’ using ultracold helium
This experimental project, involves building an ultra-stable frequency laser which will be used to probe electronic transitions in ultracold - 3He and 4He. These measurements will then be used to determine the differential isotopic nuclear charge radius of helium to a world leading absolute accuracy.
Interactions between antimatter and ultracold atoms
Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project will investigate how antimatter and matter interact by experimentally studying the interaction of positrons (the electron anti-particle) with trapped ultracold rubidium atoms.

Experimental quantum simulation with ultracold metastable Helium atoms in an optical lattice
This project will construct a 3D optical lattice apparatus for ultracold metastable Helium atoms, which will form an experimental quantum-simulator to investigate quantum many-body physics. A range of experiments will be performed such as studying higher order quantum correlations across the superfluid to Mott insulator phase transition.
Mass-entangled ultracold helium atoms
This experimental project aims to create entangled states of ultracold helium atoms where the entanglement is between atoms of different mass. By manipulating the entangled pairs using laser induced Bragg transitions and measuring the resulting correlations, we will study how gravity affects mass-entangled particles.
How does a quantum system reach equilibrium?
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.
