Invited talk

Solitons are universal nonlinear excitations that appear in settings as varied as optics, water waves, quantum gases and superfluids [1]. While reduced models of soliton dynamics are well established, their validity and dynamical behaviour in strongly nonlinear regimes with frequent interactions remain largely unexplored experimentally. Progress has been constrained by the difficulty of...

The quantum state of a levitated nanoparticle can be achieved by cooling the center-of-mass motion to
the ground-state. Delocalizing this state to increase position uncertainty to a scale comparable to the particle's
physical size is yet to be realized. Expansion protocols for this are limited primarily by decoherence due to
photon recoil, dephasing and shot-to-shot noise. This suggests...

Levitated optomechanics provides a promising platform for precision sensing and quantum experiments with massive mesoscopic objects. The performance of optically levitated nanoparticle systems is ultimately governed by the light–matter interaction. Increasing the strength of this interaction leads to higher trap stiffness and improved measurement efficiency, the latter being particularly...

408. Coupling nuclear spins to mechanical motion

Contributed Oral

The discovery of nuclear electric resonance in a single 123Sb nucleus in silicon [1] was accompanied by a detailed, quantitative understanding of the coupling between the nuclear quadrupole moment and lattice strain. With this knowledge, it is possible to design an experiment where the nuclear spin is coherently controlled using a resonant acoustic drive, i.e. nuclear acoustic resonance (NAR)...

676. Toward mechanically-detected magnetic resonance at the single spin limit

The nitrogen-vacancy (NV) centre in diamond provides a robust platform for quantum experiments owing to the long spin coherence time of the triplet state in the NV- charge state. Nanodiamonds that host a single NV centre offer a feasible platform to demonstrate a macroscopic quantum superposition state, which possesses applications in inertial sensing and precision tests of physics. However,...
