Preprint proposes a symmetry-based link between electron spin and light polarization
Calculations on a W(110) surface connect SARPES with its inverse, but only for the corresponding time-reversed setup.
Preprint offers a computable route for a difficult N-body gravity term
In two modeled three-body systems, the regularized 2PN contribution was a small fraction of the complete 2PN acceleration, while distance perturbations oscillated rather than accumulating steadily.
Preprint reports a quantum-simulation method that closely matches exact dynamics in a small model
The approach reproduced several signals in a six-site hard-core boson ring, but its dipole-correlation calculation remained non-exact and realistic atomic and molecular systems were not tested.
Preprint links oscillations in a quark model to negative diffusion
A higher-derivative regularizer removes the oscillations in the reported calculation, but the result has not been tested beyond the model’s Local Potential Approximation.
Preprint maps three ways circularly polarized light can rotate idealized particles
A classical model finds field-following rotation at low frequencies and two different high-frequency scaling laws, but offers no new experiment.
Preprint: Oxygen dopants cluster in stretched regions of a cuprate film
Three-dimensional electron imaging found more interstitial oxygen where neighboring copper atoms were farther apart, but the result is an association and alternative defect structures remain unresolved.
Preprint: Coding agents turn to agent-facing files more than traditional technical docs
An analysis found documentation was nearly as likely to be produced as consulted, while code changes usually came first.
Preprint finds the Cayley form is not the only 4-form that can define a metric
A formal study on an eight-dimensional vector space broadens the picture while leaving a central non-degeneracy conjecture unanswered.
Preprint sets out a stack-based route to rigid cohomology
The theoretical work links an arithmetic de Rham stack with overconvergent crystals, arithmetic D-modules and Hyodo–Kato constructions under explicit mathematical conditions.
Preprint: Low-power EEG chip targets real-time decoding of auditory attention
The 22-nm design reports 7.34-millisecond processing and bit-true agreement with its software model, but its power figures are simulated and patient-level validation is still ahead.
Preprint finds indirect stability certification used fewer samples in noisy system tests
In a simulated five-dimensional system with three switching modes, it reached a 95% certificate at about 800 samples, versus about 2,200 for the direct method.
Preprint finds AI planner failed without a solver in a scheduling test
Direct Qwen-Plus scheduling produced no feasible plan in 20 trials; storage rules rejected every violation, while delegated solver calls returned the correct result in 10 of 10.
Preprint finds AI models scored worse with retrieved memories
In a 1,050-case stress test, every evaluated memory strategy trailed a no-memory baseline; a prompt-based safeguard improved scores in some settings.
Preprint finds AI contract checks falter when errors require context
A benchmark of 10 language models found stronger results on explicit defined-term problems than on errors involving parties and capitalization.
Preprint gives exact tests for when QK functions fit into L2
The theorem-driven study links bounded and compact embeddings to dyadic and semidefinite capacities, then applies the criteria to Volterra and multiplication operators.
Preprint reports 8.55× faster robot action generation
RoMAN-Flow combines likelihood-based offline reinforcement learning with one-step distillation and was tested on simulation benchmarks and four real-world manipulation tasks.
Preprint reports physics-based system for removing glasses from video
JFSnet posts benchmark results for images and video, but its performance on real paired footage and unfamiliar lenses remains untested.
Preprint reports proof of Bray’s conjecture on manifold volume
A theoretical argument says a narrow relaxation of curvature bounds still leaves the standard sphere as a volume ceiling, while the allowable threshold remains unspecified.
Preprint sets mathematical bounds on quantum phase transitions
A theorem for one-parameter lattice Hamiltonians places at least one transition inside a calculable interval under specific assumptions, while leaving its order and total number open.
