Under extreme conditions hydrocarbons are known to demix, forming diamond and a hydrogen-rich phase. Here, the authors probe the timescale of this process as a function of pressure and composition. Various hydrocarbon samples were compressed to between 20 and 80 GPa in diamond anvil cells prior to serial x-ray free electron laser heating and time-resolved diffraction. They find that carbon-rich precursors form diamond in 10s of microseconds over the whole pressure range, while hydrogen rich ones take longer.

Spin–orbit torque (SOT) enables electrical magnetization control in spintronic devices. Here, the authors calculate SOT in monolayer FeGeTe and FeGaTe, van der Waals ferromagnets with perpendicular magnetic anisotropy and no reliance on heavy atoms for strong spin–orbit coupling. Horizontal mirror symmetry forbids conventional in-plane spin accumulation for out-of-plane magnetization, while tilting the magnetization enables a strongly angle-dependent response. Combining density functional theory, Wannier interpolation, and Kubo formalism, they map the torque across the magnetization sphere. They reveal hidden torques on mirror-related Fe atoms up to 30 times the net torque, whose cancellation could be lifted through van der Waals engineering.

Disorder strongly modifies the collective electronic state of one-dimensional Josephson junction arrays. However, identifying types of disorder and understanding their link to collective behavior remain challenging. Here, the authors find three classes of fabrication-induced structural disorder and investigate their effects on critical-voltage scaling of arrays in the insulating state. While the scaling remains remarkably robust against some fabrication-induced variations, arrays containing nanoscale gaps exhibit significantly different behavior, demonstrating that the nature of disorder influences the collective state of the system.

Using determinant quantum Monte Carlo simulations, the authors compute here the superconducting transition temperature of the two-dimensional attractive Hubbard model near ordinary and higher-order Van Hove singularities. Contrary to conventional wisdom, the authors find that the maximal in the model occurs away from the Van Hove singularities, when the system is in the intermediate coupling regime.

The carrier mobility in many materials is dominated by scattering of the carriers with phonons. It is often calculated using only linear, one-electron–one-phonon interaction. Here, the authors present a first-principles calculation of the mobility including the nonlinear, long-range electron-phonon interaction, for the representative halide perovskite CsPbI. It is shown that the temperature dependence of the carrier mobility decreases by about 10% due to the one-electron–two-phonon interaction, which is attributed to the strong anharmonicity and low phonon frequencies present in halide perovskites.

Long celebrated in graphene, Dirac physics inspires the search for similar phenomena in magnonic systems. Here, the authors experimentally demonstrate that magnons in an epitaxial Co bilayer on Ru(0001) exhibit Dirac properties near the Brillouin zone corner. Remarkably, the substrate does not destroy the essential physics; despite breaking sublattice symmetry and opening a gap, local valley topology remains intact. Beyond opening possibilities for discovering Dirac magnons in other ultrathin 3 magnetic films, these findings hold promise for on-chip magnonic applications.

Elucidating the origin of the pseudogap remains a central challenge in copper oxide high‑ superconductors. By investigating the magnetotransport properties of Bi‑2212 and Bi‑2223 single crystals, the authors demonstrate here that the pseudogap and superconducting fluctuations are distinct phenomena. Their results strongly suggest that the pseudogap arises from preformed Cooper pairing in the BCS–BEC crossover regime, imposing stringent constraints on theoretical descriptions of high‑ cuprates beyond the conventional BCS paradigm.
