  • Encouraging students to take ownership of their learning can improve their outcomes. This Perspective discusses ways to achieve this in the context of physics education and how digital technology can help Gen Z students in particular.

  • The concept of temporal mode-locking has been leveraged to study the interplay between laser mode-locking and photonic lattices that exhibit non-Hermitian topological phenomena. The results suggest new opportunities to study nonlinear and non-Hermitian topological physics as well as potential applications to sensing, optical computing and frequency-comb design.

  • Excitation of magnons — quanta of spin-waves — in an antiferromagnet can be used for high-speed data processing. The addition and subtraction of two such modes opens up possibilities for magnon-based information transfer in the terahertz spectral region.

  • Electric dipoles are common in insulators, but extremely rare in metals. This situation may be about to change, thanks to flexoelectricity.

  • Ageing is a non-linear, irreversible process that defines many properties of glassy materials. Now, it is shown that the so-called material-time formalism can describe ageing in terms of equilibrium-like properties.

  • Interacting emitters are the fundamental building blocks of quantum optics and quantum information devices. Pairs of organic molecules embedded in a crystal can become permanently strongly interacting when they are pumped with intense laser light.

  • Some quantum acoustic resonators possess a large number of phonon modes at different frequencies. Direct interactions between modes similar to those available for photonic devices have now been demonstrated. This enables manipulation of multimode states.

  • The integration of theory and experiment makes possible tracking the slow evolution of a photodoped Mott insulator to a distinct non-equilibrium metallic phase under the influence of electron-lattice coupling.

  • Quantum simulators can provide new insights into the complicated dynamics of quantum many-body systems far from equilibrium. A recent experiment reveals that underlying symmetries dictate the nature of universal scaling dynamics.

  • Some cerium and uranium compounds exhibit unusual transport properties due to localized electron states. Recent experiments demonstrate that quantum interference on frustrated lattices provides an alternative route to this behaviour.

  • It has long been predicted that spin-1/2 antiferromagnets on the kagome lattice should feature a series of plateaus in the change of its magnetization under an applied magnetic field. A quantum plateau of this kind has now been observed experimentally.

  • Some exotic metals exhibit competing electronic states that can be influenced by small perturbations. Now, a study of a kagome superconductor shows that this competition is exquisitely sensitive to weak strain fields, providing insight into its anomalous electronic properties.

  • When cracks creep forward in our three-dimensional world, they do so because of accompanying cracks racing perpendicular to the main direction of motion with almost sonic speed. Clever experiments have now directly demonstrated this phenomenon.
