The Fermi liquid state in highly doped superconducting cuprates is normally thought of as disordered. Now, an observation of broken mirror symmetry in that phase suggests otherwise.

- Spontaneous breaking of mirror symmetry in a cuprate beyond critical doping
- Carrier density crossover and quasiparticle mass enhancement in a doped 5<i>d</i> Mott insulatorNature Physics, Published online: 02 August 2024; doi:10.1038/s41567-024-02564-3 The pseudogap in cuprates is often linked to superconductivity. Now bulk evidence for a pseudogap is found in doped non-superconducting Sr2IrO4, revealing that pseudogaps in doped Mott insulators are not necessarily a precursor to superconductivity.

- Flow physics guides morphology of ciliated organsNature Physics, Published online: 29 July 2024; doi:10.1038/s41567-024-02591-0 The ducts of many fluid-pumping organs feature cilia. Two structural parameters organize the different types of ducts into a continuous spectrum between ciliary carpet and flame designs depending on the fluid-pumping requirements.
- Dark states of electrons in a quantum system with two pairs of sublatticesNature Physics, Published online: 29 July 2024; doi:10.1038/s41567-024-02586-x The identification of dark states—quantum states that do not interact with photons—in real materials may help to address many unsolved issues in condensed-matter physics. Now, they have been identified in palladium diselenide.
- Scalable spin squeezing from finite-temperature easy-plane magnetismNature Physics, Published online: 29 July 2024; doi:10.1038/s41567-024-02562-5 Generating highly squeezed states for quantum sensing requires precise entanglement properties, which makes it a hard task. Now a conjecture identifies a realistic regime of magnetic order at finite temperatures that enables scalable spin squeezing.
- Precise control and non-destructive readout of quantum states of ion motionNature Physics, Published online: 29 July 2024; doi:10.1038/s41567-024-02599-6 A quantum control technique is used to directly couple trapped-ion motional modes with high fidelity, enabling non-destructive measurements of the quantum harmonic oscillator states of atomic motion. The strong coupling rate and precise manipulation of the quantum states achieved with this technique could lead to advances in quantum information processing.
- A single quantum dot passively mediates entanglementNature Physics, Published online: 29 July 2024; doi:10.1038/s41567-024-02582-1 Creating entangled photon pairs often requires intense excitation of nonlinear materials or the active manipulation of quantum devices. Now, entanglement between two photons has been created by scattering a laser off a passive quantum dot.
