This paper proposes a novel framework utilizing entropy-mediated energy dissipation and new parameters like the entropy dissipation coefficient and stress gradient to better explain and quantify the asymmetric deformation and fracture mechanisms in Si-C-N hard coatings, offering an alternative to conventional thin film fracture mechanics.
This paper presents a reproducible model study of the [[7,1,3]] Steane code under correlated noise, demonstrating that a hidden-Markov decoder leveraging syndrome history significantly outperforms stationary decoders while simultaneously proving an information-theoretic limit where distinct physical fault channels can produce identical syndrome histories, making perfect recovery impossible for any syndrome-only controller.
This paper establishes a finite-size reliability map for non-Hermitian effective descriptions by deriving a conservation-integral theorem that quantifies the drift between postselected and unconditional dynamics, revealing a universal scaling law for the failure threshold that depends on excitation number and system size to provide platform-independent design rules for dissipative quantum experiments.
This paper establishes a regulator-resolved framework that distinguishes finite local information capacity from spatial lattice spacing and coarse-graining scales, deriving operational error bounds and an effective sigma-model action, and validating the approach through numerical tests on a Klein–Gordon chain to provide a controlled foundation for finite-information models without asserting a unique theory of quantum gravity.
This study demonstrates that surface preparation of grip-optimized climbing shoe rubber decouples normal detachment resistance from tangential slip initiation, revealing that pull-off performance cannot reliably predict friction behavior and that both surface state and counter-surface texture must be controlled for accurate performance evaluation.
Using adiabatic real-time time-dependent density functional theory, this study characterizes the optical response and photoexcited-carrier dynamics of the Na20@C240 core-shell nanostructure, revealing a fragmented plasmon-like resonance in the Na20 core, mixed molecular-polarization modes in the C240 shell, and complex antiphase coupling that redistributes energy toward resonant electron-hole channels with hot carriers ultimately concentrating on the fullerene cage.
This study utilizes a dual-mode measurement technique to characterize the temperature-dependent complex permittivity of lunar regolith simulants (JSC-1A and NU-LHT-4M) up to their melting points, providing critical data to optimize microwave heating processes for future lunar construction and in-situ resource utilization.
This study combines shock-tube experiments and CFD simulations to demonstrate that optimizing internal orifice geometry, particularly using continuously diverging profiles, and strategically arranging porosity gradients significantly enhance blast-wave attenuation in rigid porous plate arrays beyond the effects of porosity alone.
This paper employs a spin-dependent Cornell potential within first-order perturbation theory to accurately predict the mass spectra and decay properties of bottomonium and bottom-charm mesons, achieving high agreement with experimental data and demonstrating the framework's effectiveness through the inclusion of QCD running coupling effects.
This paper introduces a receiver-limited Fisher information framework that separates state-level sensitivity from channel and readout constraints, revealing how realistic experimental factors like measurement errors and calibration uncertainty fundamentally alter the performance and optimal operating conditions of quantum sensors.
