Nonlinear mode interactions under parametric excitation in a YIG microdisk

This paper experimentally and theoretically demonstrates how nonlinear interactions between quantized spin-wave modes in a YIG microdisk, driven by two-tone parallel pumping, exhibit controllable non-commutative behaviors dependent on mode selection and detuning, offering a scalable platform for neuromorphic and unconventional computing.

Re-evaluating photoluminescent defects in Cu2_2O

Using density functional theory with rigorous convergence and consistency checks, this study refutes the long-held assignment of specific photoluminescence lines in Cu2_2O to copper and oxygen vacancies, demonstrating instead that oxygen interstitials, copper interstitials, and a specific split copper vacancy are the only native defects responsible for robust in-gap states.

Qubit Noise Spectroscopy of Superconducting Dynamics in a Magnetic Field

This paper demonstrates that magnetic noise spectroscopy using a proximate single spin qubit serves as a powerful, non-invasive probe to quantitatively characterize superconducting dynamics in a magnetic field, successfully distinguishing between critical pairing fluctuations and various vortex phases while extracting key physical parameters like oscillation frequencies and diffusivity.

Chiral and bond-ordered phases in a triangular-ladder superconducting-qubit quantum simulator

Using a superconducting-qubit quantum simulator to realize a triangular-ladder Bose-Hubbard model with tunable synthetic magnetic flux, the authors experimentally characterize and identify distinct quantum phases, including chiral superfluids, Meissner superfluids, and bond-ordered insulators, demonstrating the platform's capability to probe strongly correlated and frustrated many-body systems.

Luttinger's Theorem Violation and Green's Function Topological Invariants in a Fractional Chern Insulator

Using exact diagonalization of the fermionic Harper-Hofstadter-Hubbard model, this study demonstrates the violation of Luttinger's theorem in fractional Chern insulators and elucidates how the fractional many-body Chern number and integer Green's function invariants are encoded in the Středa responses of the Luttinger integral and count, respectively, while proposing an experimental protocol to extract these topological invariants via local density-of-states measurements.

Spontaneous Polarization Suppression of Exciton-Exciton Annihilation in 3R-Stacked MoS2_2 Bilayers

This study demonstrates that the spontaneous polarization inherent in 3R-stacked MoS2_2 bilayers suppresses exciton-exciton annihilation through repulsive dipole-dipole interactions, thereby enabling high-density excitonic regimes essential for efficient optoelectronic applications.
