Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

Nonreciprocal Genuine Microwave Entanglement via Magnon Kerr Nonlinearity

open access: yesPhotonics
We present a utilization of the magnon Kerr effect to generate nonreciprocal genuine microwave entanglement in a hybrid system consisting of a yttrium iron garnet (YIG) sphere and three microwave cavities.

Species interactions shape the thermal performance curve and distribution of tropical Drosophila species

open access: yesEcology, Volume 107, Issue 7, July 2026.
Abstract Decades of research have demonstrated the importance of temperature in dictating species distributional limits. We know species interactions also play a key role, but we lack a predictive framework for understanding when and where species interactions will be more important than temperature in shaping distributional limits.

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 7, Page 1185-1196, July 2026.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

open access: yesSmall, Volume 22, Issue 37, 2 July 2026.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Kerr nonlinearity induced nonreciprocity in dissipatively coupled resonators

open access: yesPhysical Review Research
Nonlinearity-induced nonreciprocity is studied in a system comprising two resonators coupled to a one-dimensional waveguide when the linear system does not exhibit nonreciprocity.

Soil Moisture Impact on Convective Initiation

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Noise-resistant optomechanical entanglement via cross-Kerr effect

open access: yesFundamental Research
We propose a scheme to achieve entanglement between cavity mode and mechanical mode by breaking dark mode (DM) effect via cross-Kerr effect. This DM induced by the coupling of multiple degenerate mechanical modes to a common cavity mode, is decoupled ...

Higher‐Order Interactions Can Promote Coexistence by Rewiring Intransitivities Into Competitive Networks

open access: yesEcology Letters, Volume 29, Issue 7, July 2026.
We integrate natural history and theory to show how higher‐order interactions (HOIs) can restructure competitive networks and influence coexistence in a tropical ant community. The HOI from a parasitoid of the dominant ant species forces the community to move between two dominance regimes, and the interregnum between regimes has multiple interacting ...
