Nodal solutions for Schrodinger-Poisson type equations in R^3
Electronic Journal of Differential Equations, 2016 In this article, we consider the existence of nodal solutions for the Schrodinger-Poisson type problem \begin{gather*} -\Big(a+b\int_{\mathbb{R}^3}|\nabla u|^2\,dx\Big)\Delta u+V(|x|)u+\varphi u =|u|^{p-2}u,\quad\text{in }\mathbb{R}^3, \\ -\Delta ...

Advanced Materials, EarlyView.Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

A Note on Massively Parallel Implementation of FETI for the Solution of Contact Problems
Advances in Electrical and Electronic Engineering, 2017 The paper deals with the solution of large multibody contact problems using massively parallel computers and domain decomposition methods. These methods can solve the problems discretized by billions of nodal variables at the cost nearly proportional to ...

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Spectrum, global bifurcation and nodal solutions to Kirchhoff-type equations
Electronic Journal of Differential Equations, 2018 In this article, we consider a Dancer-type unilateral global bifurcation for the Kirchhoff-type problem $$\displaylines{ -\Big(a+b\int_0^1 | u'|^2\,dx\Big)u'' =\lambda u+h(x,u,\lambda)\quad\text{in } (0,1),\cr u(0)=u(1)=0.

Giant Bulk Photovoltaic Effect in Two‐Dimensional Topological Ferroelectric Semimetal
Advanced Science, EarlyView.ABSTRACT Ferroelectric (FE) metals have attracted growing interest because they combine ferroelectricity with metallic behavior and enable polarization‐controlled band topology near the Fermi level. However, the number of known ferroelectric metals is still limited.
