16/10/20: James Millen and I wrote a review on exploiting quantum physics with microscale particles, which appeared on the arXiv today!

Addressed to a scientific, non-expert audience.

31/07/20: Our paper on the quantum version of the tennis racket effect appeared in PRL! It demonstrates that tennis-racket oscillations turn persistent for quantum rotors, and that this effect is observable with nanoparticles and molecules.

17/07/20: Our paper on Bragg diffraction of large organic molecules was published in PRL and selected as an Editor’s Suggestion! A popular summary of our work is featured in Physics and in Chemistry World.

22/06/20: Our latest preprint reports the first experimental demonstration of Bragg diffraction of large organic molecules!

09/06/20: Levitating a nanoparticle with an elliptically polarized tweezer inside a high-finesse cavity can cool the rotational and translational motion of the particle into its 6D quantum groundstate.

Today, our preprint Cooling nanorotors by elliptic coherent scattering appeared on the arXiv.

30/05/20: In our most recent work, we show how highly charged nanoparticles levitated in Paul traps can be coherently interfaced with superconducting qubits.

For more details, check out the preprint Quantum electromechanics with levitated nanoparticles on the arXiv!

06/05/20: Our manuscript Orbital angular momentum interference of trapped matter waves appeared as a Rapid Communication in Phys. Rev. Research!

A quantum particle confined to a ring geometry can only assume discrete values of the angular momentum. This gives rise to a novel quantum interference effect, allowing geometric phases and interatomic scattering lengths to be determined with high precision.

04/02/20: Our paper Entangling levitated nanoparticles by coherent scattering was published as a Rapid Communication in Phys. Rev. A!

It demonstrates how two nanoscale objects can be entangled by coherent scattering into a common cavity mode. Congratulations Henning!

26/11/19: Had a fun evening at Cafe Scientifique in Harpenden! I talked about macroscopic superposition tests and used the opportunity to play a round of our quantum card game with the audience. Cheers!

15/11/19: SuperPosition – our quantum card game! The first deck of cards just arrived, more details will follow!
27/09/19: Had a great weekend at the first Generation |Y> Quantum meeting in Schladming, Austria!

16/09/19: Our paper ‘Macroscopicityof quantum mechanical superposition tests via hypothesis falsification‘ appeared in Physical Review A!

In this manuscript, we show how Bayesian hypothesis falsification can be used to quantify how macroscopic a given quantum superposition test is.

20/08/19: I just returned from this year’s Gordon’s Research Conference on Quantum Control of Light and Matter, at Salve Regina University in Newport, RI.
30/07/19: From the 699th Wilhelm and Else Heraeus-Seminar on Levitated Optomechanics in Bad Honnef, Germany!

27/06/19: Our paper ‘Decoherence of non-relativistic bosonic quantum fields‘ appeared as a Rapid Communication in Physical Review A!

Together with Marduk Bolanos and Klaus Hornberger from the University of Duisburg-Essen we show how to describe the classicalization dynamics of bosonic quantum fields, which will be useful for experiments with continuous degrees of freedom. Thanks for your work Marduk and Klaus!

01/06/19: Lukas Martinetz from the University of Duisburg-Essen visited me last week at Imperial College. We had a productive time and discussed the latest developments in James Millen’s lab!

01/05/19: New preprint ‘Decoherence of non-relativistic bosonic quantum fields’ online! It presents a general Markovian master equation describing the classicalization of non-relativistic bosonic quantum fields. Well done Marduk!

01/05/19: My first day at Imperial College London! Happy to be here and looking forward to exciting physics.
