  • Physical networks are systems composed of physical entities, which conventional graph-based approaches fail to capture. Theoretical work now introduces a meta-graph technique to uncover the impact of physicality on the structure of networks.

  • A decade ago, the anti-laser made waves as a new type of perfect absorber that functions as a one-way trap door for light. Experiments have now demonstrated the control of light without absorbing it.

  • Network geometry is an emerging framework used to describe several topological and organizational features of complex networks. Now this approach has been extended to directed networks, which contain both symmetric and asymmetric interactions.

  • A detailed understanding of phonon transport is crucial for engineering the thermal properties of materials. A particular doping strategy is now shown to lead to good thermoelectric performance with low thermal conductivity.

  • Landau’s theory of Fermi liquids predicts that impurities embedded in a Fermi sea of atoms form quasiparticles called polarons that interact with one another via the surrounding medium. Such mediated polaron–polaron interactions have been directly observed and are shown to depend on the quantum statistics of the impurities.

  • Despite the theoretical prediction of spinaron quasiparticles in artificial nanostructures, experimental evidence has not yet been seen. Now it has been observed in a hybrid system comprising Co atoms on a Cu(111) surface.

  • A nonlinear optical approach has now enabled picosecond control of a complex band structure, driving a non-Hermitian topological phase transition across an exceptional-point singularity.

  • The simulation of open quantum many-body systems is one of the hardest tasks in computational physics. Now, quantum computers are close to answering crucial questions for such systems in a regime that classical computers cannot reach.
