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.

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 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 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 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 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 model-based arXiv preprint examines how structured driving fields could control the geometry and geometric phases of high-harmonic optical cat states. Its results are theoretical calculations, not an experimental demonstration.

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 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 version-1 arXiv preprint reports that a conformal-field-theory construction organized several kinds of post-quench dynamics in interacting non-Hermitian quantum-chain models. Parameters fixed from static data predicted later return, local and spatial behavior, with especially close matches in the Yang–Lee benchmark. The evidence is analytic and numerical, finite-size and model-specific.

A structured model for identifying the source of synthetic speech performed almost perfectly on the ASVspoof2019-attr-17 benchmark, but the result is limited to known generators and the study’s tested conditions.

A mathematical preprint finds that allowing the boundaries of a modeled polymer to move changes the predicted probabilities and timing of translocation. The results are exact for the Brownian model but remain theoretical, while the fractional-Brownian extension is numerical.

A modeling preprint finds that finite shell thickness changes the predicted resonance map of core–shell spheres. Its resonance classifier performs strongly across three modeled contrast regimes, while its recurrence relation covers only the sound-speed-driven and mixed regimes.

A preprint reports that tested quarter-filled calculations remain finite at high nonlinear Drude-weight orders, contrary to a low-energy prediction of divergence. At half filling, the weights vanish in the thermodynamic limit and follow a size-dependent exponential pattern.

A preprint presents an implicit neural representation for designing three-dimensional point-spread functions. The reported tests included rotating helixes, an extended-depth-of-field pattern and multifocal designs, but the evidence is qualitative and limited to a described optical setup.

A laboratory preprint reports electron-drift oscillations at the lower-hybrid frequency in an electron-only reconnection outflow. Linear calculations predict strong instability growth, and a scaled simulation reproduces the broad pattern, but the evidence remains tied to one laboratory configuration.

A computational study of high-harmonic generation in thin silicon slabs found that propagation depth and observation geometry changed the modeled spectrum. An alternative propagation method agreed with the full Maxwell calculation in some low-order cases but produced a model-sensitive high-order cutoff.

A new arXiv preprint uses a modeled spin-torque microwave detector to test whether one average voltage can identify one property of a repeating positive pulse when the other two are known. The analysis reports a clear linear response for in-plane dynamics and a nonlinear response under some out-of-plane conditions.

An arXiv preprint proposes TCPα, a post-hoc confidence method for music-information-retrieval models. In tests spanning rāga identification, domain shift and ornamentation detection, it reported stronger failure-prediction performance than comparison targets and improved results when low-confidence predictions were rejected.

A preprint proposes a trajectory-level framework for non-Markovian jump processes and applies it to thresholded BK-channel records. Conventional dwell memory was higher in cell-BK patches, while a state-and-age response residual was much higher in mitoBK patches.

Organic transistors containing platinum nanoparticles showed a reported memory window greater than 20 volts and electrical behavior the authors describe as Coulomb-blockade-like.

An arXiv preprint reports spectral features in optically excited MnBi₂Te₄ that its authors interpret as signatures of a nonequilibrium exciton condensate and a BEC–BCS crossover. The measurements do not directly establish condensate coherence, leaving the interpretation model-dependent.
