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.

You can find a free video & audio recording of my Optomechanics tutorial lecture from SPIE Optics + Photonics 2017, by clicking on the image below: You can site it in the following way: James Millen, “Tutorial on optomechanics (Conference … Continue reading →

It only took 308 days, but we just had some new research published in Nature Communications. It was a completely surprising piece of work; we were able to levitate a tiny silicon cylinder, and make it tick like the hands … Continue reading →

I was fortunate enough to be invited to give not one, but two lectures at this exciting, interdisciplinary meeting. I discussed working with nanoparticles in high vacuum, and also presented The Quantum Workshop, which the organisers had kindly shipped all … Continue reading →

I wrote a short Viewpoint article for Physical Review X, giving an overview of some very exciting work in the field of nanothermodynamics, where researchers have surpassed the Carnot limit of efficiency.

I am extremely honoured to have received the Institute of Physics’ Bates Prize. You can read the citation here. It is a particular pleasure to belong to a list including my Master’s project supervisor (Mike Tarbutt), my Ph. D. supervisor … Continue reading →

    I have thoroughly enjoyed attending the Optical Trapping and Optical Micromanipulation meeting at SPIE Optics and Photonics 2017 in San Diego. I delivered a tutorial lecture on Optomechanics and chaired a session on levitated optomechanics. You can find … Continue reading →

I had an great day hosted by Klemens Hammerer, giving a talk on our research and visiting various labs. I particularly enjoyed seeing a rocket which launched cold atoms into space, and the 10m LIGO prototype.

Very happy to speak about Rotational Optomechanics at the Highland Spring School on Mesoscopic Physics, organized by the Czech Academy of Sciences. AND it took place in a physics castle!
