Berry curvature dipole generation and helicity-to-spin conversion at symmetry-mismatched heterointerfaces

The Berry curvature dipole (BCD) is a key parameter that describes the geometric nature of energy bands in solids. It defines the dipole-like distribution of Berry curvature in the band structure and plays a key role in emergent nonlinear phenomena. The th ...

Fiber-interface directional coupler inscribed by femtosecond laser for refractive index measurements

Jiangtao Zhou, Zhechen Zhang, Yiping Wang, Jiachen Wang

A novel fiber-interface directional waveguide coupler was inscribed on the surface of a coreless fiber by femtosecond laser, and was successfully applied to highly sensitive refractive index (RI) measurements. The primary arm was first inscribed to couple ...

Mixed strain-displacement finite elements for landslide and avalanche release prediction

Lorenzo Benedetti

Determination of the initial detaching volume is one of the major challenges in snow avalanche and debris flow forecast. Soil liquefaction due to loss of cohesion results in landslides, whereas quasi-brittle failure triggers the release of snow avalanches. ...

Mixed stabilized finite element methods in nonlinear solid mechanics. Part III: Compressible and incompressible plasticity

Lorenzo Benedetti

This paper presents the application of a stabilized mixed strain/displacement finite element formulation for the solution of nonlinear solid mechanics problems involving compressible and incompressible plasticity. The variational multiscale stabilization i ...

UV-extending ghost inflation

Sergey Sibiryakov, Mikhail Ivanov

We present a setup that provides a partial UV-completion of the ghost inflation model up to a scale which can be almost as high as the Planck mass. This is achieved by coupling the inflaton to the Lorentz-violating sector described by the Einstein-aether t ...

Tuning Uranium-Nitrogen Multiple Bond Formation with Ancillary Siloxide Ligands

Marinella Mazzanti

The new homoleptic ate U(III) siloxide [K(18c6)][U(OSi(O tBu)3)4] 2 was prepared in 69% yield by reduction of [U(OSi(OtBu)3)4] 3 with KC 8. The reaction of the neutral U(III) siloxide complex [U(OSi(O tBu)3)2(μ-OSi(OtBu) 3)]2 1 with adamantyl azide leads t ...

Tangible Paper Interfaces: Interpreting Pupils' Manipulations

Pierre Dillenbourg, Frédéric Kaplan, Patrick Jermann, Quentin Bonnard

Paper interfaces merge the advantages of the digital and physical world. They can be created using normal paper augmented by a camera+projector system. They are particularly promising for applications in education, because paper is already fully integrated ...

Synthèse d'images moiré

Sylvain Chosson

We explore a new approach for synthesizing moiré images that can be used for authentication of documents. For synthesizing moiré images, we need two layers: a base layer made of replicated bands or parallelograms and a revealing layer made of transparent l ...
