Research

I research cold atom technologies to study the fundamentals of science. I am currently developing a new detector for dark matter and gravitational waves with the AION consortium (https://aion-project.web.cern.ch). This detector is based on atom interferometry with ultracold strontium, where clouds of atoms are separated and recombined to give information about the difference in the paths they travel. I am particularly interested in researching new methods of cooling and manipulating atoms, and lead a team developing techniques for transport and cooling of ultracold strontium. I also work on a quantum simulation experiment, where cold atoms trapped in lattices of laser light are used to create an experimental simulation of the quantum behaviour of real materials.

You can find out more about these projects here.

Schools and public engagement

I love discussing science, and thinking of interesting and interactive ways to share the incredible research I’m lucky enough to see and take part in. I have run science workshops with the Jesus College Intellectual Forum and Cambridge Festival, and various initiatives with the Cavendish Laboratory and Cambridge colleges.

With funding from the Cambridge University Public Engagement Fund I run workshops  for primary school groups (KS2) about atoms, their uses and how we study them. If you represent a school and would like to work with me please get in touch by email.

Hubbard Models for Quasicrystalline Potentials

13 October 2022

Our latest work on creating Hubbard Models for Quasicrystalline Potentials is now on the Arxiv (2210.05691). In it, we present a numerical method for constructing the Hubbard Hamiltonian of non-periodic potentials without making use of Bloch's theorem, and then apply it to the eightfold rotationally symmetric 2D optical...

AION Vacuum system arrived

4 July 2022

The AION experiment reached an important first milestone with the UHV vacuum chamber having been delivered. Next stop: laser cooled Strontium. aion_uhv_chamber.jpg

News & Views on first-order phase transition

31 March 2022

Bryce Gadway wrote a News & Views article for Nature Physics on our paper on Realizing Discontionuous Phase Transitrions. Check it out: https://www.nature.com/articles/s41567-022-01543-w

Towards quantum simulation of false vacuum decay

20 January 2022

In our lastest work we have used a resonantly driven optical lattice to turn the Mott transition into a first-order (discontinuous) transition. We were able to directly observe the associated hysteresis and metastability, where the system remains stuck in its original phase (the false vacuum) even though the ground state...

First AION collaboration workshop

11 November 2021

Finally, we were able to hold teh first in-person collaboration of the new AION collaboration, where we want to develop large scale atom interferometers. aion_collaboration_nov21_2mp.jpg
