When Does Fuzzy Adaptation Earn Its Complexity? A Calibration-Aware Computational Study of Finite-Shot Entanglement Detection

This computational study evaluates three measurement-allocation strategies for finite-shot entanglement detection across varying detector conditions, finding that while a fuzzy-adaptive approach maximizes detection power under uncertain calibration and drift, it does not consistently minimize estimation error or strictly control false-positive rates, thereby highlighting the need to balance detection gains with robustness and accuracy.

Observation of light-induced Haldane gap in graphene

This study reports the first direct observation of a light-induced Haldane gap in monolayer graphene, demonstrating that circularly polarized light dynamically breaks time-reversal symmetry to open a topologically nontrivial gap and engineer ultrafast controllable quantum phases.

Cosmological Acceleration from Scale-Space Metric Enthalpy Degradation: A Thermodynamically Consistent Resolution to the Dark Energy Problem

This paper proposes a thermodynamically consistent resolution to the dark energy problem by deriving cosmic acceleration from first principles as an irreversible enthalpy degradation process at horizon scales, successfully reproducing the observed age of the universe and transition redshift while preserving standard structure formation.

Resource map of quantum reservoir computing against tuned classical baselines

This paper introduces a rigorous benchmark protocol that accounts for measurement costs and tuned classical baselines, demonstrating that quantum reservoir computing offers no general advantage over classical methods and only outperforms them in specific oracle-based scenarios where the benefit stems from the input access model rather than the reservoir itself.

Spectral origin and decoupling cost of non-Markovian ergotropy revivals in quantum batteries

Using numerically exact hierarchical equations of motion, this study demonstrates that non-Markovian ergotropy revivals in quantum batteries are physical phenomena driven by spectral weight rather than memory, but their net utility is fundamentally limited by the work cost required to decouple the battery from its environment.

Machine learning prediction of hydrogen sorption properties of zirconium-titanium based C14 Laves phase AB 2 alloy from chemical composition

This study demonstrates that machine learning models trained on elemental atomic percentages can effectively predict key hydrogen sorption properties of Zr–Ti-based C14 Laves phase AB2 alloys, achieving high accuracy for unit cell volume and moderate accuracy for equilibrium pressure, thereby accelerating the design of hydrogen storage materials.

All Paths All at Once: A Quantum Monte Carlo and Neural Committor Approach to Reaction Pathway Search

The paper introduces tReax_expedition, an energy-only method that combines coupled Monte Carlo exploration with stochastic quenching and restrained continuation to successfully identify competing reaction pathways and resolve saddle energies without requiring potential-energy gradients or prior transition-state guesses.

The general Stokes’ theorem as the mechanism for synchronizing 2s2p electrons within a neon atom

This paper proposes a novel geometric framework for the neon atom's 2s and 2p electrons, interpreting them as orthogonal four-dimensional structures (points, arcs, surfaces, and solids) whose cyclic transformations and synchronization are governed by the general Stokes' theorem and related integral theorems, thereby offering a unified perspective that extends to biological systems.

Modeling of Rayleigh-type waves in a viscoelastic piezoelectric fiber-reinforced composite layered Structure

This paper investigates the propagation of Rayleigh-type waves in a viscoelastic piezoelectric fiber-reinforced composite layer bonded to an isotropic elastic half-space via an imperfect interface, deriving an exact dispersion relation to analyze how fiber volume fraction, constituent viscoelasticity, and interfacial compliance influence wave phase velocity, attenuation, and electromechanical coupling.

Fracture Mechanics and Self-Healing in Molecular Crystal Resonators for Lasing

This study demonstrates that single crystals of the organic optical material HDMAC can undergo self-healing of microscale cracks and fractures induced by an AFM tip, effectively restoring their structural integrity and essential optical waveguiding and resonator properties required for lasing applications across different crystallographic orientations.
