Levitated Nanophysics Group

Congratulations to Katie for defending her thesis “Levitated Electromechanics for Probing Fundamental Physics”. Many thanks to Dr. Janet Anders & Professor Peter Barker for doing the examination.

Yanhui is the first PhD student to graduate from the group, with his thesis entitled “Rotational Optomechanics”. Many thanks to Dr. Dave Phillips (Exeter) and Dr. Michael Vanner (Imperial) for their thorough 3.5hr examination.

After 3 years in the group, we were sad to say goodbye to Maryam this week. We wish her all the best in her new job at Alphasense and her surely stellar career in the future.

We are excited to share our work on using levitated particles to probe structured light, we have discovered a new type of optical angular momentum. Read all about it on arXiv.

Congratulations to Yugang, Katie & Muddassar, and the three generations of Masters students who worked on this project!

The group is lucky enough to welcome two King’s Undergraduate Research Fellows into the group this Summer. Coco is working on our public engagement project Seeing the Unthinkable, and Seraphine is exploring the potential to build hybrid nanoparticle control platforms.

We are pleased to share our work on event-based imaging of levitated nanoparticles! We believe this is an exciting new technology to leverage in the study of levitated systems, particularly for the study of multiple particles. It’s particularly gratifying that this work involves three generations of Masters students, and well done to Yugang for doing the work in the lab to get the paper into a publishable form.

We were interviewed about our collaboration with artist Steven Claydon by Stephanie Reed, you can read the article here: King’s Artists project combines quantum physics and art to explore the invisible.

We helped to organize Guiding Lights 2022, the London Light’s celebration of the UNESCO International Day of Light. See the Public Engagement page for more details, and enjoy this summary video!

We were very fortunate to have Ruvi Lecamwasam from the Quantum Machines group at OIST visit us for a week. We put him to work on our Event Camera project!
