Infinitely many sign-changing solutions for a Schr
We study a superlinear Schrödinger equation in the whole Euclidean space ℝn. By using a suitable sign-changing critical point, we prove that the problem admits infinitely many sign-changing solutions, under weaker conditions.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Infinitely many periodic solutions of Duffing equations under integral condition [PDF]
In this paper, we study the multiplicity of periodic solutions of a Duffing equation $$ x''+g(x)=p(t). $$% By using the generalized Poincaré-Birkhoff fixed point theroem, we prove that this equation has infinitely many periodic solutions provided $g ...

Infinitely Many Periodic Solutions for a Fractional Problem Under Perturbation [PDF]
We discuss the existence of infinitely many periodic weak solutions for a subcritical nonlinear problem involving the fractional operator (− Δ + I)s on the torus TN. By using an abstract critical point result due to Clapp [14], we prove that, in spite of

Infinitely many solutions for hemivariational inequalities involving the fractional Laplacian
In the paper, we consider the following hemivariational inequality problem involving the fractional Laplacian: {(−Δ)su+λu∈α(x)∂F(x,u)x∈Ω,u=0x∈RN∖Ω, $$ \textstyle\begin{cases} (-\Delta )^{s}u+\lambda u\in \alpha (x) \partial F(x,u) & x \in \varOmega ...

Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Infinitely Many Nonradial Solutions of a Euclidean Scalar Field Equation [PDF]
We study the equation −Δu + b(|x|) u = ƒ(|x|, u), x ∈ RN;u ∈ H1(RN). The existence of a nonradial solution has been an open problem for some time even in the autonomous case.
