- Synthetic cells get into shape
- Strongly interacting Meissner phases in large bosonic flux laddersNature Physics, Published online: 02 May 2025; doi:10.1038/s41567-025-02890-0 The quantum simulation of driven, strongly correlated phases at large scales is challenging, primarily due to detrimental heating effects. Now, a large-scale interacting Mott–Meissner phase has been realized in a neutral atom quantum simulator.
- Observation of the diffusive Nambu–Goldstone mode of a non-equilibrium phase transitionNature Physics, Published online: 02 May 2025; doi:10.1038/s41567-025-02902-z Gapless modes emerging from non-equilibrium phase transitions are predicted to diffuse rather than propagate as sound waves. Now, the diffusion of these modes and their suppression under symmetry breaking are confirmed in a polariton condensate.
- Altermagnet with a metallic touchNature Physics, Published online: 02 May 2025; doi:10.1038/s41567-025-02894-w Metallic altermagnets — distinct from conventional ferromagnets and antiferromagnets — hold potential for advanced spintronic applications. Now, experiments reveal room-temperature altermagnetism with antisymmetric spin polarization in a metallic oxide.
- Observation of Floquet–Bloch states in monolayer grapheneNature Physics, Published online: 01 May 2025; doi:10.1038/s41567-025-02888-8 Monolayer graphene has been long proposed as a candidate system for Floquet engineering. Time- and angle-resolved photoemission spectroscopy measurements now show the formation of Floquet–Bloch states in this material.
- Collective quench dynamics of active photonic lattices in synthetic dimensionsNature Physics, Published online: 01 May 2025; doi:10.1038/s41567-025-02880-2 Synthetic dimensions allow photons and gauge fields to interact in photonic emulators. Now a study with fast-gain lasers shows that gain-driven coherence enables robust light flow in frequency space, establishing it as a viable platform for lattice emulation.
- Microscopic signatures of topology in twisted MoTe<sub>2</sub>Nature Physics, Published online: 01 May 2025; doi:10.1038/s41567-025-02877-x The topological properties of twisted bilayer MoTe2 are thought to stem from a spatial texture in the layer polarization of the electronic wavefunctions. This polarization is now measured using scanning tunnelling microscopy.
- Thermopower reveals localized electronsNature Physics, Published online: 01 May 2025; doi:10.1038/s41567-025-02896-8 Thermopower measurements on magic-angle twisted bilayer graphene reveal strong electronic correlations and their contribution to entropy.
