Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, Volume 11, Issue 10, 22 May 2026.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Eye can see clearly now: Identifying the locus associated with a white‐eye mutation in honey bees (Apis mellifera)

Insect Molecular Biology, Volume 35, Issue 2, Page 209-215, April 2026.
We performed a community science investigation with the beekeepers nationwide to find phenotypic mutants. Alongside a beekeeper in Kentucky, we performed a GWAS to identify a region associated with a white‐eye phenotype. We identified an eight bp region in a non‐coding RNA strongly associated with white eyes.

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

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
The four‐wave mixing conversion efficiencies of both the waveguides and the microresonators exhibit a well‐correlated relation versus their effective lengths, confirming the unified theoretical framework. These experimentally validated findings offer a fresh perspective on Kerr nonlinearity and pave the way toward advancing the development of highly ...

How Important Is Pay and What Are the Effects (Positive and Negative) of Pay for Performance?: Evaluating Claims and Evidence

Human Resource Management, Volume 65, Issue 2, Page 531-559, March/April 2026.
ABSTRACT Compensation plays a pivotal role in shaping employee behavior, motivation, and well‐being. Although extant research has explored various dimensions of compensation, questions about how important pay is to employees and concerns (on the part of employers and/or employees) about the unintended negative (in addition to intended positive ...

Numerical modelling of frequency comb generation in nonlinear resonators [PDF]

, 2016
We present a comprehensive review of recent work on numerical modelling of frequency comb generation in coherently-driven nonlinear resonators. Specifically, we discuss modelling and nonlinear dynamics of frequency combs generated in Kerr nonlinear ...

Nearly quantum-limited Josephson-junction Frequency Comb synthesizer [PDF]

, 2020
While coherently-driven Kerr microcavities have rapidly matured as a platform for frequency comb formation, such microresonators generally possess weak Kerr coefficients; consequently, triggering comb generation requires millions of photons to be ...
