Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves

open access: yesAdvanced Physics Research, Volume 5, Issue 5, May 2026.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Non‐stationary forest responses to hotter droughts: a temporal perspective considering the role of past legacies

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to a highly uncertain future.

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

open access: yesArchaeometry, Volume 68, Issue S2, Page S88-S103, May 2026.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Cavity magnomechanics: from classical to quantum

open access: yesNew Journal of Physics
Hybrid quantum systems based on magnons in magnetic materials have made significant progress in the past decade. They are built based on the couplings of magnons with microwave photons, optical photons, vibration phonons, and superconducting qubits.

Goal Hierarchies: Understanding Sub‐Goal and Primary Goal Interdependency

open access: yesJournal of Management Studies, Volume 63, Issue 3, Page 1403-1443, May 2026.
Abstract There is increased research on how organizations respond to performance feedback on multiple goals. Most of it considers goals that have ambiguous ranking and thus differs from goal hierarchies with sub‐goals that are instrumental for accomplishing a primary goal.

Non-Gaussian state preparation and enhancement using weak-value amplification

open access: yesnpj Quantum Information
We introduce a protocol for generating non-Gaussian (nG) states via postselected weak measurement. The scheme involves injecting an arbitrary quantum state and a single photon into the signal and idler ports of an interferometer with a third-order ...

Are physiological oscillations physiological?

open access: yesThe Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Experimental Demonstration of Unified Kerr Nonlinear Effective Lengths for Gallium Phosphide‐On‐Insulator Photonic Devices

open access: yesAdvanced Photonics Research
Field enhancement (FE) plays a pivotal role in boosting the four‐wave mixing conversion efficiency (FWM CE)in photonic resonant cavities. While previous studies typically attributed this enhancement to intracavity power buildup, fewer have linked it to ...
