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.
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!
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.
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!
01/05/19: 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!
