Entanglement Before Geometry: Random Tensor Networks as the Quantum Completion of the Flux-Gauge Area Law

This paper bridges the gap between combinatorial flux-gauge models and quantum tensor networks by demonstrating that SU(N) link ensembles constitute exact tensor networks whose random intertwiner distributions and renormalization-group structure naturally reproduce the Ryu–Takayanagi area law, thereby establishing a rigorous quantum derivation of emergent spacetime geometry from gauge-theoretic microstates.

Geometry-resolved avalanche criterion in disordered spin systems: transverse connectivity corrections and asymptotic recovery of the flat-front law

This study demonstrates that while the many-body localization avalanche criterion asymptotically recovers a simple area-dependent law at strong disorder, finite-width disordered spin systems exhibit systematic, geometry-dependent corrections to their stability driven by transverse connectivity and closed loops, thereby explaining the slow growth of apparent critical disorder with system width and providing a quantitative framework for interpreting MBL crossovers in higher dimensions.

Improvements on quantum designated verifier signature based on Bell states

This paper identifies a forgery vulnerability in Xin et al.'s Bell-state-based quantum designated verifier signature scheme and proposes a more secure and practical alternative using single qubits and unitary operations that eliminates the need for a trusted center and quantum entanglement resources.

Physics-guided mechanistic residual learning for sparse-condition force prediction in S45C end milling

This study proposes a physics-guided mechanistic residual learning framework that combines an interpretable single-active-edge model with a neural network trained to learn bounded corrections, thereby achieving robust and data-efficient prediction of milling-force waveforms for S45C steel under sparse and unseen machining conditions.

Generation of bright quantum high-order harmonic driven by combined coherent and bright squeezed vacuum light

This study demonstrates that combining strong coherent and weak bright squeezed vacuum lasers to drive high-order harmonic generation in atomic gas enables the creation of bright quantum high-order harmonics, where macroscopic propagation effects and gas pressure modulate the phase and quantum properties of the resulting attosecond bursts, paving the way for attosecond quantum spectroscopy.

Benchmarking 26 DFT Functionals for Zeolites: Structural Metrics, Tetrahedron-Normalized Properties, Energetic Accuracy, and the PBE- Grimme Paradox

This study presents a comprehensive benchmark of 26 DFT functionals against experimental data for four zeolite frameworks, introducing tetrahedron-normalized metrics to identify GGA-HCTH as the optimal general-purpose functional, m-GGA-M06-L for electronic properties, and GGA-PBE-Grimme for thermodynamic accuracy despite its reliance on error cancellation.

Accurate estimation of velocity and acceleration, their statistics and position prediction in Lagrangian Particle Tracking

This study introduces complementary adaptive filtering, track-merging, and statistical noise correction strategies to accurately estimate instantaneous Lagrangian velocities and accelerations and their statistics from noisy particle tracking data, overcoming the biases and limitations of conventional global filtering methods.

Chirality-Enhanced Two-Photon Absorption with Asymmetric Vortex Beams in Twisted Gold Nanorods

This study introduces a vortex offset technique using asymmetric Laguerre–Gaussian beams to drive two-photon absorption in twisted gold nanorods, achieving single-particle chiral sensitivity 10^5-fold greater than conventional methods by defining a new momentum dichroism parameter that captures combined spin and orbital angular momentum effects.

Spectral Tunable Room Temperature Superfluorescence

This paper proposes a state-entropy framework and a novel excitation strategy to achieve spectrally tunable, multi-stage room-temperature superfluorescence in NaNdF₄ nanocrystals, expanding the emission range from two orange-red bands to six distinct bands across the ultraviolet-to-red spectrum while enabling real-time enhancement and potential applications in on-chip ultrafast optical computing.

Does energy-parity subtraction render induced gravity finite?

This paper demonstrates that introducing a soft Z2 energy-parity doubling of the vacuum resolves the long-standing counterterm obstruction in Sakharov's induced gravity by lowering the divergence degree of heat-kernel sectors, thereby rendering Newton's constant and black-hole entropy finite, covariantly related quantities derived from the same integral at the one-loop level.
