Today we published our latest work on holographically generated spatial light potentials on arxiv:
Rapid stochastic spatial light modulator calibration and pixel crosstalk optimisation
https://arxiv.org/pdf/2408.07672
I am really excited about this work as it makes using these potentials not only better but also much easier, which ultimately will allow more people to use this technqiue in their experiments.
The University of Strathclyde has made me a Research Fellow at the Physics department this spring. Naturally this is great news for me. It allows me more freedom to persue the research I find most interresting and promising and will allow me to build up my own team and ultimately my own experiment.
I will continue to work with our Quantum Gas Microscopes and use these to study fundamental physics question and further devellop related quantum technology applications.
2024 started with some good news, our first paper from the new Rb quantum gas microscope was accepted for publication in Nature Communications.

A second paper was submitted for review this month from Elmar Hallers experiment in which we studied periodic driving in titlked optical lattices. A technique that sounds complicated and exotic but which ahs shown in recent years to be key to many quantum simulation experiments in which rich badmstructures are created and studied!
I am happy to see that our latest paper was published this week in Physical Review Research. Because it combines new experimental results with theoretical simulations this is one of the longest papers I have worked on. We first show where a shaking with a lattice can lead to the growth of excitations in a condensate. Then we devellop the required theoretical description to show how this stabiliy diagram can be understood by considering modulational instabilities.

Last week our latest paper was published in Scientific Reports! We are now able to create holographic light potentials for ultracold atoms with record breaking accuracy and efficiency.

I submitted a simulation paper last week and it is now availeble on arxiv: https://arxiv.org/abs/2207.08663
This project started during the C19-lockdowns in which our labs were closed. We simulated quantum gas microscope data and studied the limitations of single atom imaging. We compared analysis techniques and discovered the best way to retrieve the locations of the atoms in a lattice.
The recently submitted work from my time in Paris got accepted for publication by New Journal of Physics. I am both happy and thankful that it went so fast and smooth from submission to publication. It is a bit technical and practical but it shows the experiment that I worked on really well!

Last month we submitted a paper from my time in Paris describing the experiment I helped to build.
“An optical elevator for precise delivery of cold atoms using an acousto-optical deflector”

Last Friday our work on driven solitons with negative effective mass was published in Physical Review Letters!
