A trion fluid—which forms when excitons bind to an extra electron or hole—is expected to exhibit a Hall effect in magnetic fields. Now, this is demonstrated in electron–hole double layers. nature.com/articles/s41567-0…

Random access memory is an important element of classical computers, but equivalent schemes for quantum computers are much less mature. Now an eight-qubit random access memory has been demonstrated using superconducting circuits. nature.com/articles/s41567-0…

By combining quantum and relativistic physics, it is possible to verify someone’s position remotely without needing to trust them. Such a position verification protocol has now been introduced and demonstrated with a quantum optics experiment. nature.com/articles/s41567-0…

Altermagnetic states hold promise for spintronic applications but are yet to be observed in twisted van der Waals materials. Now an orthogonally twisted CrPS₄ homostructure is shown to exhibit signatures of altermagnetism. nature.com/articles/s41567-0…

Driving a solid with light can create a topological insulator, but controlling its electrons has remained elusive. Optical control of electrons in a Floquet topological insulator has now been achieved in light-dressed graphene. nature.com/articles/s41567-0…

Creation and annihilation of topological defects are prevalent in active materials. It is now shown that in living systems with nematic order, polar propulsion breaks mirror symmetry during these processes. doi.org/10.1038/s41567-026-0…

Systems of coupled self-propulsive components, both biological and synthetic, display coordinated dynamics. Experiments with 3D printed motors now show that rotary motion can lead to spatiotemporal order as well as disorder-induced wave propagation. nature.com/articles/s41567-0…

Wigner crystals have been observed in transition metal dichalcogenides, but their collective excitations have not been shown. Now the signatures of these excitations are revealed in the optical spectra of a charge-tunable monolayer semiconductor. nature.com/articles/s41567-0…

Understanding the time-resolved dynamics of antiferromagnetic skyrmion interactions remains a challenge, limiting control over their collective behaviour. Now their ultrafast dynamics is visualized in real time in thin-film multilayers. nature.com/articles/s41567-0…

Dualities between different models are an important tool in theoretical many-body physics. Here a constructive recipe is given for topological interfaces between dual models that are transparent to wavepackets but alter their properties. nature.com/articles/s41567-0…
