- Cavity electrodynamics of van der Waals heterostructuresNature Physics, Published online: 20 October 2025; doi:10.1038/s41567-025-03064-8 Integrating an electronic device with a cavity can cause the electrons to couple to photons strongly enough to form hybrid modes. Now, the cavity effects induced by intrinsic graphite gates are shown to modify the low-energy properties of graphene.
- Demonstration of dynamic surface codesNature Physics, Published online: 17 October 2025; doi:10.1038/s41567-025-03070-w Typical quantum error correcting codes assign fixed roles to the underlying physical qubits. Now the performance benefits of alternative, dynamic error correction schemes have been demonstrated on a superconducting quantum processor.
- Electrons herald non-classical lightNature Physics, Published online: 16 October 2025; doi:10.1038/s41567-025-03033-1 When free electrons emit light, an entangled electron–photon state is created. Here measurements of the correlated multiparticle system have been used to produce non-classical photonic states.
- Vibrational responses of polar skyrmionsNature Physics, Published online: 15 October 2025; doi:10.1038/s41567-025-03068-4 Controlling polar skyrmions — topological textures of electric dipoles — is crucial for modern optoelectronic applications. Terahertz excitation is shown to govern ultrafast manipulation of polar skyrmions featuring signature vibrational modes.
- Nodal hybridization in a two-dimensional heavy-fermion materialNature Physics, Published online: 14 October 2025; doi:10.1038/s41567-025-03060-y Anisotropic hybridization between conduction and unpaired f electrons is rarely observed. Now, a lanthanide-based two-dimensional compound exhibits nodal hybridization, giving rise to heavy-fermion behaviour.
- Experimental observation of a time rondeau crystalNature Physics, Published online: 14 October 2025; doi:10.1038/s41567-025-03028-y Previous work on periodically driven many-body systems has demonstrated the formation of time crystals that break time-translation symmetry. Now, more general phases with partial temporal ordering have been realized.
