Together with Jan Gieseler, I wrote a literature review of experiments where levitated nanoparticles are used to test thermodynamics on the nano-scale:
Levitated Nanoparticles for Microscopic Thermodynamics—A Review
J. Gieseler & J. Millen, Entropy 20, 326 (2018)
I’m pleased to announce that I’ve moved to King’s College London, as a Lecturer in Advanced Photonics. I will be continuing my research on rotational opto- and electro-mechanics.
New paper online! In this work, we propose a feasible experiment for measuring orientational revivals with a 50nm long cylinder. This is a purely quantum effect, arising from quantization of angular momentum, and interference of different orientations.
Every two years, I love to attend the Gordon Research Conference, “Mechanical systems in the quantum regime”, which brings together the biggest names in my field, with an encouragement to present breaking results.
This year was particularly exciting for me, as for the first time I presented a poster on my very own work (see below), and I was invited to deliver a “Hot Topic” talk on our research in Vienna.

Here, we propose a new scheme, where levitated particles are coupled to, and controlled by, electrical circuits. To be built soon!
Levitated electromechanics: all-electrical cooling of levitated nano- and micro-particles
Our work on detection of nanoparticles in Silicon microcavities has been published in Applied Physics Letters. This technology will be really important for controlling smaller nanoparticles, and in turn realising a quantum physics with massive objects.
