Emergent Spacetime from a Dark-QCD Correlation Medium

This paper presents a generally covariant effective field theory completion of a speculative model where a confining dark QCD sector generates emergent spacetime, demonstrating that specific structural separations regarding dark-color singlets, universal metrics, mobile dark hadrons, and internal fibers are necessary to resolve previous empirical conflicts and exactly reproduce general-relativistic predictions, including the Schwarzschild geometry and PPN parameters, while explicitly acknowledging that the model relies on matching conditions rather than deriving fundamental constants from first principles.

Programmable Raman Scattering through Quasi-BIC Pump Gating and Stokes-Sideband Routing

This paper introduces a hybrid plasmonic–photonic platform that utilizes quasi-bound states in the continuum (qBICs) to transform surface-enhanced Raman scattering (SERS) into a programmable process capable of momentum-selective gating, spectral routing, and polarization-controlled amplification, achieving significant enhancement factors and the ability to selectively promote specific vibrational sidebands.

Effect of Salt Concentration on Resistive Switching behavior in Ion Conducting Polymer film based heterostructure

This study demonstrates that optimizing the salt concentration in PVDF-based polymer electrolyte films effectively engineers trap states to enable stable bipolar resistive switching with a high on/off ratio and long retention, governed by a transition from trap-controlled space-charge-limited conduction to ionic conduction.

Optimization of optoelectronic performance in magnetron-sputtered ITO thin films via coupled regulation of Ar:O₂ ratio and sputtering power

This study systematically demonstrates that the optoelectronic performance of magnetron-sputtered indium tin oxide (ITO) thin films is optimized through the coupled regulation of sputtering power, which governs crystallinity and electrical behavior, and the argon-to-oxygen ratio, which tailors crystal orientation, carrier concentration, and optical transparency via oxygen vacancy modulation.

A Broadband Grating–Split Resonator Transmissive Metasurface for Efficient Terahertz Linear Cross-Polarization Conversion Based on Characteristic Mode Analysis

This paper presents a novel three-layer grating-split resonator transmissive metasurface that achieves ultra-broadband (0.35–1.45 THz) and highly efficient (>99%) linear cross-polarization conversion through the synergistic electromagnetic coupling of metallic gratings and asymmetric split-ring resonators, as validated by Characteristic Mode Analysis.

Monotonic increase of conductivity with non-monotonic defect content: ZnO thin films at precursor molar concentrations of 0.3–0.5 M

This study of ultrasonic spray pyrolysis-grown ZnO thin films reveals that a widely used diagnostic for hopping conduction is an artifact of fixed-frequency analysis, while demonstrating that charge-transport parameters vary monotonically with precursor concentration despite non-monotonic changes in defect content and surface morphology.

Topological signatures in the curvature-induced energy response

This paper demonstrates that while the leading first-order curvature-induced energy response in the nonrelativistic Haldane model is nonuniversal and bond-dependent, the third-order response exhibits a universal discontinuity across the topological transition that aligns with relativistic gravitational Chern–Simons predictions, thereby preserving a topological fingerprint beyond the relativistic limit.

Beyond sensitivity: mechanism-resolved error budgets for designing quantum sensors

This paper introduces a framework that generates mechanism-resolved error budgets from a single open-system simulation to reveal how distinct physical mechanisms independently limit a quantum sensor's sensitivity, accuracy, and robustness, demonstrating that optimizing for sensitivity alone can lead to significant accuracy failures.
