    Self-reinforcing light pulses known as solitons are fundamental structures in wave dynamics. Previously, solitons could be produced only by bench-top lasers, but they can now also be generated using chip-sized mid-infrared lasers. This innovation enables the development of portable, efficient tools for use in spectroscopy, environmental sensing and medical diagnostics.

    In heavy-fermion compounds, hybridization between mobile charge carriers and localized magnetic moments gives rise to exotic quantum phenomena. The discovery of heavy fermions in a van der Waals metal that can be peeled apart to a layer a few atoms thick allows these phenomena to be studied and manipulated in two dimensions.

    Supersolids are long-sought-after quantum materials with two seemingly contradictory features: a rigid solid structure and superfluidity. A triangular-lattice cobaltate material provides evidence for a quantum spin analogue of supersolidity, with an additional giant magnetocaloric effect — discoveries that pave the way for helium-free cooling to temperatures below 1 kelvin with frustrated quantum magnets.
