An oscillator-driven femtosecond pump–probe system measured local optical dynamics in multilayer and monolayer MoS₂. The reported setup combined an estimated whole-spectrum time resolution below 100 fs with submicrometre spatial resolution and found different long-lived responses at the centre and edge of one monolayer flake.

A laboratory preprint followed reconstituted skim-milk casein micelles through camel-chymosin hydrolysis and gelation. An intermediate-scale scattering feature faded before aggregation, while a second high-q peak became visible; the authors say the pattern is consistent with κ-casein having an internal structural role, but the simulations do not uniquely define the micelle.

Researchers found a linked set of thermal, motion and magnetic-topology signatures in a selected solar brightening. The authors describe the pattern as consistent with reconnection involving a twisted magnetic structure, but not as proof that reconnection occurred.

A new arXiv preprint describes a matrix-free way to estimate precision limits in dynamical quantum measurements when conventional matrix methods become singular. Analytical derivations and numerical examples suggest the proposed bound can track variance changes more closely than the standard quantum Cramér–Rao bound in selected models.

A modeling preprint argues that unusually steep modulus–density relationships in open-porous solids may partly reflect how their internal networks change as density changes, rather than a different local deformation mode. The framework is analytical and illustrative, with no physical specimens, empirical dataset or independent validation reported.

A laboratory preprint describes quantum imaging with undetected photons, using a visible camera readout to recover information from an infrared object. The demonstrations report a broad imaging range, spatial-resolution measurements and a faster single-frame mode, but rely on simple test materials and estimated detector comparisons.

A preprint reports that a single optical waveguide can concentrate light near its surface and was associated with a higher probability of detecting fluorescence from individual atoms. At zero transport displacement, the reported detection probability was 20% with nanolensing—four times the result without it.

A model of pure SU(3) gluon matter produces a pronounced near-transition rise in specific heat and a rapid increase in compression response, with both approaching high-temperature plateaus.

A modeling preprint proposes judging stellarator confinement by whether an orbit-selected drift surface closes inside the plasma, even when it is misaligned with flux surfaces. The results are analytical and computational, and the framework does not yet cover several important orbit-loss regimes.

A mathematical preprint develops geometric quantities for studying entanglement in bipartite quantum-state space. It derives general bounds for the entangled weight in a Best Separable Approximation and gives more explicit formulas in the two-qubit case.

A preprint comparing stiff three-atom molecular and atomistic glass models found higher reported elastic moduli and larger quasilocalized-vibration proxies in the molecular model, along with stronger dilation-to-shear coupling in nonlinear plastic modes. The authors say effective-degree-of-freedom corrections bring some measures closer, but the simulations do not test real or polymeric glasses.

A preprint on entanglement manipulation reports that arbitrary correlated catalysts do not erase every limitation in its finite-dimensional PPT framework. For the state ρ_v, the reported correlated-catalytic PPT distillation rate remains below the corresponding entanglement cost.

An arXiv preprint reports that two constructive “shadow” methods can approximate trained quantum machine-learning models used for cloud-cover prediction, sometimes with lower mean squared error under finite-sampling tests. The study is an offline computational evaluation, not evidence of a quantum advantage or improved climate simulation.

A mathematical preprint finds that local spinor responses near a fixed BTZ horizon can retain whether a singular coupling follows an inverse-radial or inverse-square profile, even after the coupling values are matched. The result is local and does not provide a global BTZ spectrum.

A theoretical calculation coupling freezing gravity to a minimally coupled perfect fluid retains the model’s separation between background and perturbation physics and its linear large-scale freezing. It also derives analytic conditions for ghost and gradient stability, while leaving nonlinear behavior and strong coupling unresolved.

The study models a family of asymptotically de Sitter spacetimes and compares their simulated shadows, photon rings and axial gravitational quasinormal modes. Its main contrast is between modest optical changes and more pronounced shifts in part of the calculated spectrum.

Researchers tested locally generated continuous-variable quantum key distribution over a deployed hybrid channel and used adaptive post-processing to handle fluctuating transmission. The reported rates were asymptotic, and the finite-size analysis did not produce a positive composable key under the experimental parameters.

A laboratory preprint reports that 1T-TaS2 crystals followed sharply different transformation patterns during cooling and heating. The measurements and a phenomenological model point to branch-specific kinetics, but do not establish the microscopic cause or its wider relevance.

A theoretical preprint uses graph-based constructions to challenge a universal inverse-square bound relevant to Pauli shadow tomography. The construction exceeds the proposed scaling for its mathematical families, while weaker polynomial bounds and triply efficient protocols remain possible.

A preprint analyzing three selected YBCO weak links reports an association between higher focused-helium-ion dose, lower critical current and lower IcRn, while normal resistance rose. The authors say the pattern is consistent with reduced interface transparency and fewer effective conducting channels, but those features were inferred from transport rather than directly measured.

A preprint reports a numerical design in which vertical modulation controlled conversion between two modeled waveguide modes, while horizontal routing largely avoided that same transition. The simulations also show that horizontal writing-position errors can open leakage into a third mode.

A computational preprint tests SAKE, a local automatic-differentiation method for transporting nonlinear spectroscopic responses between nearby quantum models.

An arXiv preprint describes RL-Trotter, a DDPG-based policy that chooses Trotter step sizes from conservation-law observations and accumulated evolution time. In numerical benchmarks, it had lower reported errors than conventional fixed-step Trotterization and ADA-Trotter, while the evidence remained computational.

A modeling study describes how a two-color ultrashort laser pulse with a changing focal velocity could shape terahertz radiation. The calculations produced a parabolic wavefront in one decelerating case and a conical, ring-shaped pattern for a constant-velocity comparison, while also showing limits at the highest tested velocity.

A new arXiv preprint describes ONEX, a compiler built around the structure of product-based quantum error-correction codes. In computational benchmarks and noise simulations, it produced shorter execution plans and lower modeled logical error rates than the tested baselines.
