Emergence of Rashba Spin‐Orbit Coupling in Staggered‐Gyromagnetic Photonic Crystals
Laser &Photonics Reviews, EarlyView.Rashba spin‐orbit coupling emerges in a staggered‐gyromagnetic photonic crystal under a uniform out‐of‐plane magnetic bias. The staggered magnetization splits a four‐fold Dirac point into a Rashba band structure carrying helical spin textures, verified by a four‐band k‐p model.

SUBCRITICAL QUADRATIC NONLINEAR SCHRÖDINGER EQUATION
, 2011 We study the initial value problem for the quadratic nonlinear Schrödinger equation [Formula: see text] where γ > 0. Suppose that the Fourier transform [Formula: see text] of the initial data u1satisfies estimates [Formula: see text], where ε > 0 ...

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

EvolvED: Evolutionary Embeddings to Understand the Generation Process of Diffusion Models
Computer Graphics Forum, EarlyView.EvolvED visualises how diffusion models generate images by embedding intermediate outputs to preserve semantics and evolutionary structure. It supports analysis via (a) user‐defined goals and prompts, (b) sampling intermediate images, (c) extracting relevant features, and (d) visualising them in structured radial and rectilinear layouts for ...

Auxin response and PIN‐mediated transport in chlorophyte algae
Journal of Integrative Plant Biology, EarlyView.Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Continuum limit of 3D fractional nonlinear Schrödinger equation [PDF]
In this paper, we investigate the continuum limit theory of the fractional nonlinear Schrödinger equation in dimension 3. We show that the solution of discrete fractional nonlinear Schrödinger equation on hZ^3 will converge strongly in L^2 to the ...

Inverse problems for semilinear elliptic PDE with a general nonlinearity a(x,u)$a(x,u)$
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract This article studies the inverse problem of recovering a nonlinearity in an elliptic equation Δu+a(x,u)=0$\Delta u + a(x,u) = 0$ from boundary measurements of solutions. Previous results based on first‐order linearization achieve this under a sign condition on ∂ua(x,u)$\partial _u a(x,u)$, and results based on higher order linearization ...
