Nature Physics, Published online: 25 July 2024; doi:10.1038/s41567-024-02589-8The tuneable and nonlinear nature of the interactions between two optically levitated nanoparticles allows the observation of the system’s non-Hermitian dynamics and a mechanical lasing transition.

Nature Physics, Published online: 25 July 2024; doi:10.1038/s41567-024-02536-7Error mitigation has helped improve the performance of current quantum computing devices. Now, a mathematical analysis of the technique suggests its benefits may not extend to larger systems.

Nature Physics, Published online: 25 July 2024; doi:10.1038/s41567-024-02593-yExperiments show that the shape of a biofilm, not just its cell doubling time, significantly impacts its expansion rate. This insight could guide new strategies for controlling biofilm growth.

Nature Physics, Published online: 25 July 2024; doi:10.1038/s41567-024-02588-9Tuneable optical control enables the investigation of collective phases of motion in a pair of coupled levitated mechanical oscillators.

Nature Physics, Published online: 25 July 2024; doi:10.1038/s41567-024-02590-1Non-reciprocal interactions between two optically levitated nanoparticles allow the observation of non-Hermitian dynamics and a mechanical lasing transition, and suggest applications in optomechanical sensing.

Nature Physics, Published online: 22 July 2024; doi:10.1038/s41567-024-02553-6Many 2D or 1D materials feature fascinating collective behaviour of electrons that competes with highly localized interactions at atomic defects. By combining terahertz spectroscopy with scanning tunnelling microscopy, the ultrafast motion of these collective states can be...
