Intertwined orders in a quantum material
Nature Physics, Published online: 11 July 2025; doi:10.1038/s41567-025-02942-5
Symmetry-protected topological orders are often in competition with electronic correlations that tend to induce orders with broken symmetry. Now, a quantum material is shown to exhibit correlation-driven tuneable excitonic instabilities intertwined with symmetry-protected topological orders.

Measurement of phonon angular momentum
Nature Physics, Published online: 11 July 2025; doi:10.1038/s41567-025-02952-3
Theory predicts that phonons—quanta of lattice vibrations—can carry finite angular momentum and thus influence physical properties of materials. Now phonons with angular momentum have been seen in tellurium with a chiral crystal structure.

Topological excitonic insulator with tunable momentum order
Nature Physics, Published online: 11 July 2025; doi:10.1038/s41567-025-02917-6
Experimental systems in which non-trivial topology is driven by spontaneous symmetry breaking are rare. Now, topological gaps resulting from two excitonic condensates have been demonstrated in a three-dimensional material.

First-principles diagrammatic Monte Carlo for electron–phonon interactions and polaron
Nature Physics, Published online: 10 July 2025; doi:10.1038/s41567-025-02954-1
Diagrammatic Monte Carlo calculations accurately describe polarons in different theoretical models. Now, integrating this with accurate first-principles calculations can describe the ground-state and dynamic properties of polarons in real materials.

Nanophotonic quantum skyrmions enabled by semiconductor cavity quantum electrodynamics
Nature Physics, Published online: 09 July 2025; doi:10.1038/s41567-025-02973-y
Quantum optical skyrmions are promising for quantum photonic applications but have not been experimentally realized. Now nanophotonic quantum skyrmions are generated using a semiconductor quantum dot–Gaussian microcavity quantum electrodynamics system.

QED tests in strong fields
Nature Physics, Published online: 09 July 2025; doi:10.1038/s41567-025-02959-w
High-precision measurement of the hyperfine splitting in a radioactive isotope of hydrogen-like bismuth unlocks new possibilities for testing quantum electrodynamics in extreme magnetic fields and for probing nuclear structure.

Ytterbium dopants for quantum simulation
Nature Physics, Published online: 09 July 2025; doi:10.1038/s41567-025-02948-z
Understanding and controlling many-body interactions is essential for advancing quantum science. A crystal containing millions of strongly interacting ytterbium ion dopants has now been used to simulate complex quantum many-body phenomena.

Quantum thermalization and Floquet engineering in a spin ensemble with a clock transition
Nature Physics, Published online: 09 July 2025; doi:10.1038/s41567-025-02943-4
Using Floquet engineering, an ensemble of ytterbium-171 ions in an yttrium orthovanadate host crystal provides a platform for studying the dynamics of different quantum many-body models, including the realization of a time-crystalline phase.
