Lagrangian chaos and the enstrophy cascade in Ekman-Navier-Stokes two-dimensional turbulence

This paper investigates how linear Ekman friction alters the enstrophy cascade in two-dimensional turbulence by demonstrating that, under high friction, vorticity becomes passively transported, allowing a phenomenological model based on Gaussian-distributed Lagrangian Finite Time Lyapunov Exponents to accurately predict the resulting spectral slope corrections.

A tractable framework for phase transitions in phase-fluctuating disordered 2D superconductors: applications to bilayer MoS2_2 and disordered InOx_x thin films

This paper develops a self-consistent microscopic thermodynamic framework that unifies fermionic quasiparticles, Coulomb-regularized phase fluctuations, and BKT vortices to explain how disorder and carrier density drive the separation between the superconducting gap and transition temperature in 2D systems, successfully reproducing experimental results for bilayer MoS2_2 and disordered InOx_x films.

Measurements of differential charged-current cross sections on argon for electron neutrinos with final-state protons in MicroBooNE

The MicroBooNE collaboration presents the first single-differential electron-neutrino charged-current cross-section measurements on argon with final-state protons, reporting a total cross section of [4.1±0.3 (stat.)±1.1 (syst.)]×1039cm2/nucleon[4.1 \pm 0.3 \text{ (stat.)} \pm 1.1 \text{ (syst.)}] \times 10^{-39} \mathrm{cm}^{2}/\mathrm{nucleon} that shows good agreement with standard neutrino event generator predictions.

Nodal structure of bound-state wave functions for systems with quartic dispersion

This paper analyzes the nodal structure of bound-state wave functions in one-dimensional quantum systems with quartic dispersion, demonstrating that while the classical oscillation theorem holds in classically allowed regions, it breaks down in forbidden regions where wave functions exhibit additional nodes, a finding supported by semiclassical, variational, and exact solvable model approaches.

Instability thresholds for de Sitter and Minkowski spacetimes in holographic semiclassical gravity

This paper investigates the stability thresholds of de Sitter and Minkowski spacetimes in holographic semiclassical gravity across dimensions d=3,4,5d=3,4,5, revealing that stability depends critically on the spacetime dimension and a specific dimensionless parameter γd\gamma_d, with Minkowski spacetime being universally unstable in d=3d=3, both spacetimes becoming unstable in d=4d=4 beyond a critical threshold, and both remaining stable in d=5d=5 except where higher-curvature corrections dominate.

Qualitatively distinct mechanisms of noise-induced escape in diffusively coupled bistable elements

This paper identifies three qualitatively distinct noise-induced escape mechanisms in populations of diffusively coupled bistable elements by developing a model-reduction approach that derives specific effective dynamics for weak, intermediate, and strong coupling regimes, revealing that these mechanisms arise from the interplay of nonlinearity, coupling, and noise rather than bifurcations of the noise-free system.

Emulating the logistic map with totalistic cellular automata

This paper demonstrates that while a probabilistic totalistic cellular automaton's mean-field formulation approximates the logistic equation only with infinite-range interactions, numerical studies show that shuffling configurations or rewiring a fraction of links (including in small-world networks) effectively emulates logistic behavior and exhibits a bifurcation cascade in density, a phenomenon that also extends to deterministic totalistic automata with similar symmetries.

Systematic bias due to eccentricity in parameter estimation for merging binary neutron stars : Spinning case

This study extends previous research on eccentricity-induced systematic biases in binary neutron star parameter estimation to include spin effects, revealing that while biases in chirp mass, mass ratio, and effective spin follow predictable quadratic trends with eccentricity, biases in effective tidal deformability exhibit a complex dependence on mass and spin parameters, potentially impacting neutron star property inference.

Passive scalar cascade in the intermediate layer of turbulent channel flow for Pr1Pr\leq 1

This study investigates the similarities and differences between velocity and passive scalar scale-by-scale equilibria in turbulent channel flow with Pr1Pr \leq 1, revealing that while both fields achieve Kolmogorov equilibrium at a specific length scale rminr_{min} below the inertial range, the characteristics of this equilibrium and the nature of their interscale transfer rates exhibit distinct Prandtl number dependencies and alignment behaviors.

Coupling between thermochemical contributions of subvalence correlation and of higher-order post-CCSD(T) correlation effects -- a step toward `W5 theory'

This paper investigates the significant coupling between subvalence correlation and higher-order post-CCSD(T) effects on the total atomization energies of first- and second-row molecules, leading to a proposed "W5 theory" protocol that yields revised, highly accurate thermochemical values consistent with Active Thermochemical Tables (ATcT).
