- Topological bands and correlated states in helical trilayer graphene
- Morphometry and mechanical instability at the onset of epithelial bladder cancerNature Physics, Published online: 07 January 2025; doi:10.1038/s41567-024-02735-2 Carcinoma subtypes are normally linked to specific genetic alterations, but tissue mechanical changes also play a role. Now, aberrant morphologies resembling bladder carcinoma are shown to emerge from stiffness changes during epithelial overgrowth.
- Non-Markovian dynamics of a superconducting qubit in a phononic bandgapNature Physics, Published online: 07 January 2025; doi:10.1038/s41567-024-02740-5 Defects known as two-level systems are a major source of noise for superconducting qubits. Adding a phononic crystal is now shown to extend the lifetime of these two-level systems, which could lead to improved qubit coherence.
- A solid-state electrolyte with liquid-like vibrational characterNature Physics, Published online: 06 January 2025; doi:10.1038/s41567-024-02698-4 Solid-state electrolytes with high ionic conductivity are promising candidates for battery applications. Experiments in one of these materials now reveal a mechanism that mediates ionic diffusivity and mirrors the vibrational properties of liquids.
- Liquid-like dynamics in a solid-state lithium electrolyteNature Physics, Published online: 06 January 2025; doi:10.1038/s41567-024-02707-6 Understanding the mechanism of ionic diffusion in superionic materials is crucial for their potential applications in solid-state batteries. Now liquid-like dynamics that break the Debye law of lattice dynamics have been demonstrated in a lithium electrolyte.
- Effect of energetic ions on edge-localized modes in tokamak plasmasNature Physics, Published online: 06 January 2025; doi:10.1038/s41567-024-02715-6 Edge-localized plasma modes in a tokamak can damage its innermost wall. Simulations now show that fast ions can modify the spatio-temporal structure of these modes. These effects need to be considered in the optimization of control techniques.
- Large quantum fluctuations observed in strongly interacting bosonsNature Physics, Published online: 03 January 2025; doi:10.1038/s41567-024-02701-y Among weakly interacting bosons, quantum fluctuations are akin to those of harmonic oscillators, and they manifest themselves through positive correlations between particles of opposite momenta. A quantum-gas experiment reveals that, by cranking up the interactions, these correlations are suppressed, and hence that quantum fluctuations become strong and anharmonic.
- First-order quantum breakdown of superconductivity in an amorphous superconductorNature Physics, Published online: 03 January 2025; doi:10.1038/s41567-024-02713-8 A first-order, disorder-driven, superconductor–insulator phase transition is demonstrated. This is in contrast with the usually observed second-order transition and highlights the role of Coulomb interactions between preformed Cooper pairs.
